Well I guess they?re sorta like children, you love them each in their own way...So l?m gonna list 3.
Only judging from those I personally own.
Best looking, modern: CZ 75B Cold War Commerative 2nd gen.
Most useful: RAMI
Most emotional investment: CZ 75 pre B, Police trade-in (stripped, polished, reprofiled trigger guard, welded void uncovered by reprofiling trigger guard, hot blued, reassembled) nothing as good looking as a well polished, hot blued 75 IMO.
