Really there are a bunch of options out there, there are the punchy switches on taobao, or even the revo whites.
Ive been really getting into the frankenswitch linear craze that it seems a lot of higher end people are getting into, and from what I have found mixing different tops and bottoms and stems makes the best switches due to the sound and smoothness profiles changing.
Personally I have made some nice zeal v2 bottomed retooled black top housing revo white stemmed and springed linears that are lubed with 205g0 and they sound like a dream. Mixing milky switch parts with either aliaz or zeal (v1 or v2) is a good idea for sounds and smoothness, as well as throwing in some more vintage black or retooled black parts for more sound customizations.
Though for stock switches I do think that gateron is the way to go for linears. They have more options than that of cherry or zeal, even though those switches may be better with less(?) work. So all in all, if going for minimal work, tealios or retooled blacks, or any gateron clone switch (punchy, fei, tangerine, revo white, etc.) and for the max customization I feel like just mixing and matching different parts till you find the one that works for you is the best way to do it, albeit expensive.
