To add my voice to the crowd - Yes there's a lot of variables. There's a reason most OEMs manufacture both types of pads. There's also a reason most all of the calipers meant for road use come stock with resin pads.

You will get a more pleasant experience with resin pads.

You will get better performance (read as braking power) in wet with metal pads. Metal pads will last longer given the same conditions.

Quite literally though - YMMV

I have seen riders here in the flatlands of greater Chicago run through regular rim brake pads within a season. I have also known many, like myself, who could run the same pads for almost the life of the bike.

Some of it is terrain. Most of it is riding style.

All of this said - modern resin pads perform better for almost all riders in almost all conditions they encounter with regularity.
