If it's any solace, the K Tuned is the most "solid" and mechanical of the 3 choices on the market, incrementally so. Either of the kits are a step up above stock though, in terms of overall engagement. You trade off a bit of smoothness in the process but I feel it's a worthwhile trade.
My car definitely got smoother over time regarding shift feel, so probably wait a little bit before you change things, but the Acuity stuff is pretty great. I got the stage 2 shift kit before the full shifter was available, and it's pretty great but I did feel like I needed a super heavy shift knob to balance it back out.
