I use the Paterson tanks, mostly just because that's what I have and they've always been pretty abundant in the past. The trick with the wet-reel issues is: have more reels so you can turn over faster. (which reminds me to send an extra to photolady.)
Steel reels are superior if you're practiced at them, but not superior enough for me to worry about, is my usual thought on the matter. With some care, the Paterson reels work fine, but if you rush, you can kink your film. I like the big funnels on the Super System 4 tanks (the only ones I believe they have made for a long time at this point) both for the sake of being a little easier to deal with in the kitchen, and cause I can put the empty film canisters or spools in between the funnel and the outer lid, that way if a tank is loaded, I know exactly that something's in there, what it is, and how many of em. Also any notes I wrote on there.
