Course it has to be a CZ dont be silly
Who else makes better rimfires for anywhere near there price?
I have the classic and love it depends what you want to use it for and your taste. If your going to scope it and dont want iron sights no point going for any models with the hogsback.
For offhand field shooting id go with the varmint as the extra weight lets it balance nicely or if your using the gun on the bench the stock is shaped better.
For other field shooting id go with the american purely because i think its the nicest looking
If its going to get rough treatment style or sillouette depending if you like the stainless barrel
