What would what be? depends on the system I'm using at the time. For Nikon after selling off all of the over priced lenses I wasn't using, I used a Sigma 35mm 1.4 only for a bit, on Fuji when I first used the system I did similar, only used the 35 1.4 on my old X-T1 for ages ; on M43, with the Panasonic G80 I used only a 25mm 1.7 for a while to warm into that system, later I used only a 15mm 1.7 for months. More recently, after coming back to Fuji, I used the excellent 16mm 1.4 only for months and really enjoyed it. I think too many options cripples you in ways when you don't really have a specific agenda
