Well, it's hard to say if you have done the right purchase, if you don't know what the different switches feels like.
I simply think the blue switches requires too much force for my preference, though i love the clicky sound
The brown switches is very light to press down, but are easy to buttom down, which some ppl dont like.
The black switches requies some force aswell, but with no tactile feel/feedback.
I haven't tried the red ones.
For my use, which is typing and gaming i like brown switches the most of those.
And the mainly reason i returned the DAS was because i got tired of the Glossy finish, though i felt my fingers got fatigued typing on blue switches, even though blues are the most recommended for typing, o.O
Therefore it all comes down to preference of what type of switch you like the most.
In Denmark, i think you get most 'Bang for the buck' when buying a Steelseries. But only if you like black switches.
I haven't tried the Zowie, but if you like brown switches i would probebly go with this keyboard if you're tight on budget.
Even better, try find a used keyboard at lower prices. Mechanical keyboards last long, and usually used mechanical keyboards can offer a great deal.
I know you mentioned that you're afraid of Filcos because of 'ping'. But take a look at this guy, who is selling a Filco with blues. I once bought a Mechanical Noppoo Choc mini of him.
