Nichicon Caps - Which Series?

I'm trying my hand at piecing a cap kit together for the first time rather than ordering from Bob Roberts. I'm using Digikey. I've selected Nichicon caps, but there are a ton of different series within Nichicon for me to choose from. I'm looking at 105 degree C ones and there are PM series, PB series, PW series, etc. Looks like they mostly just differ on the lifetime rating. Some say extremely low impedance and others say high ripple current.

Recommendations on which series to get? Does it matter?
