Gotta go and feel them, because with cheaper brands while you can still get great switches, consistency is more of a problem.
Also there are a lot of subjective differences between Cherry, Kailh, Gateron, Outemu and other directly comparable switches (e.g. companies that use the same colour coding, e.g. blue for tactile clicky, black/red for linear, brown for compromise).
Then also the way the board is built and the plastic used in the keycaps can make a world of a difference with certain switches (e.g. ABS vs BPT blues), sometimes near enough to make them feel like different switches, unrecognizable even. And with cheaper boards there's gonna be a lot of variance in materials and build quality.
I'd suggest pawing them, plugging them into your laptop, testing them for a while, still checking reviews before making the decision once something catches your interest.
Outemu tends to be the cheapest of widely available dedicated switch brands, but there are also in-house switches developed by certain manufacturers that don't charge a hefty premium; you might end up liking one of those.
Re: Kailh, it can cost almost the same as Cherry, at which point I'd normally ask why bother, especially with blues.
If you're looking for something new, perhaps try out those low-profile Kailh speed switches a lot of people are in love with these days? (E.g. Sharkoon Purewriter.)
