I can imagine you have moved on from MX Blues in the meantime, but still: coming from a standard Logitech board, in terms of typing experience, this is already such an improvement! The tactility feels wonderful and much more responsive. But this is just the start: I am excited to find out what is available and possible in typing experience.
You did well to use a Logitech keyboard. They make great products, especially wireless peripherals, even if they're membrane. Indeed. have you ordered any switch testers? I think
this one is a good value. It doesn't have absolutely everything you may want to try, but it is a start. If you wanted to focus on clickies, the box switches in that tester should be an interesting comparison for you against MX. Matias switches you may need to buy in a sample pack and they won't fit in that tester, unfortunately. Their tactiles and linears are dampened and I would choose those over anything else I have tried if I wanted a quiet board, personally. Topre is a contender as well. Unfortunately, Topre switches are not self contained, so you may need to find a board to try for those (the same goes for buckling spring). Everything is a give and take though. You won't get the crisp/refined tactility of a clicky switch with a silent switch of any kind.
To friends, who think I am slightly weird in spending so much money on a keyboard, I have likened it to playing a musical instrument. A great instrument will play better, make a more pleasant sound to your ears, and make your overall experience more fun. But, as with musical instruments, one does not buy a stradivarius as first instrument: the journey itself is too much fun to skip all the intermediate steps.
We are weird, and that's fine. Life would be pretty boring if everyone were the same. Your comparison to an instrument is apt. I agree completely. Nobody has the same tastes as the person next to them either. You won't necessarily like capacitive buckling spring as much as I do, and you may find yourself preferring something like a thocky linear switch or something.
As for the boards you mention: I must admit that most of the brands you mention do not even remotely ring a bell... 
But that is the noob's prerogative! I will definitely look into the switches you mention - all for the ultimate typing experience. I hope to end up at the board that makes me jump out of bed every morning because I can type on it again!
The Model F is an IBM keyboard (of various variants) manufactured throughout the 1980s. They were primarily made for IBM's PC XT and AT computers. It was a simplification/cheapening of IBM's beam spring keyboards, which were themselves meant to recreate the sensory characteristics of a mechanical typewriter in the mid-to-late 1970s. The Model M (membrane buckling spring), iterations of which are still manufactured by
Unicomp, was a further simplification/cheapening of the Model F. They just recently
began production of a recreation of the Model M SSK for the first time, which was a TKL version of the Model M. The Model F is lighter, smoother, and has more travel before the tactile event than the Model M. They also tend to be more pingy and high-pitched than the Model M due to their construction. They are easier to service/modify because their plate sandwich can be disassembled easily whereas the Model M's inner assembly is held together with plastic rivets. Ellipse is currently selling
modern recreations of the F77 and F62, which were Model F variants that had beefy solid zinc cases.
Here's the thread on here that deals with the topic.Alps is another animal entirely. Production of Alps SKCM blue switches ceased in 1989 and they have never been faithfully reproduced. To make matters worse, they're
very susceptible to dirt and debris, and are not MX compatible in any way, so they become scarcer and scarcer by the day and have little options in terms of boards, caps, etc. Since the end of production of SKCM blue, Alps continued to produce continuously cheapened clicky successors, starting with SKCM white switches. The early SKCM whites can be almost indistinguishable from SKCM blue, but the newer they are the more they differ. Eventually Alps began producing simplified versions of their switches, and then third parties manufactured them under license. Simplified Alps have had a bumpy reputation in terms of feel, sound, and reliability. Today, Matias' switches (simplified Alps clones) are manufactured by Gaote, who also makes the Outemu line of MX clones. Personally, I think that Gaote's Matias switches are probably the best mass-produced self-contained switch in production. They may still not be quite as reliable as MX (this remains to be seen), but the whole line feel and sound so much better. Alps also made linear and tactile switches, most of which are also much loved. Alps switches were mostly in boards sold by OEMS of another name, with very few exceptions, sort of like how MX (and clones) are today.
Box switches are MX compatibles that have IP56 waterproof/dustproof ratings. Their clicky switches use a relatively new click mechanism called a click bar, which is manufactured in varying thicknesses that lend themselves to both different levels of tactility and sound and different pitches when paired with different spring weightings. Most tend to agree that this family of clickies is better in every way than MX and clones, having extremely smooth and crisp tactile events with no rattle. There are box liners and tactiles, which are themselves also pretty smooth, and their tactiles have a slightly different design than that of MX and clones. They're known to possibly turn clicky over time though, unfortunately.
You're in the right place to find that very feeling, and I hope you do. Mechanical keyboards can be such a pleasure.
