I have had both. They are very different. The power levels between them are very similar, or at least, can be very similar assuming similar calibers. In .25 my Wildcat Compact gave a maximum of about 56 FPE. I could get my 350 mm Leshiy 2 close to that, and I am sure with a 450mm barrel it would have been easy. With a 600 mm FX barrel in the L2 I was well over 60 FPE.
The Wildcat has a much better trigger and would be better for pure target work. The L2 is fine, but not a tack driver. From an ergonomic standpoint I found not much between them. They are different, but both fit me well. I found the L2 to be much louder unless one used a good silencer, such as the Mod40. With equivalent silencers they are, again pretty similar.
However, the L2 is a semi-auto. That’s totally different right there. My Wildcat was very similar to my Wildcat Sniper, and my Crowns, and my Impact. The L2 was its own thing!
I have since sold the Wildcats (not the Crowns or Impacts). I’m not selling my Leshiy 2.
