I think people are conflating the question of 'the best' with 'my favorite'. Two different things, although the results might be similar.
con?flate
/k?n?fl?t/
verb
gerund or present participle: conflating
combine (two or more texts, ideas, etc.) into one.
"the urban crisis conflates a number of different economic and social issues"
synonyms: mix, blend, fuse, unite, integrate
"the plot gets weighed down when the writers conflate too many issues into one episode"

Well Said.
So to avoid CONFLATING the issue of best 9mm; may I suggest we consider each 'manual of arms'
type of pistol separately. Some examples:
Best Striker Fired 9mm (Glocks, HK VP-9, CZ P-10); Best DA/SA de-cocker (Sigs, CZ's), Best SAO Manual Safety (1911), Best Decocker
with Safety (FNHFNXTactical,Beretta, S&W), Best DAO (Sig, S&W,Kahr), etc. Otherwise, we're talking about best type of action, not best gun. Just Say'in.
