I have specifically purchased FR-4 protoboard for a particular project for structural reasons. But 99% of my protoboard use is limited to have a place to tack down a small handful of SMD components. So the phenolic suits me just fine, being easier to cut and solder.
A downside of plated through holes is they leak solder blobs all the way out the bottom of the board, depending on what you're doing. With a SS board, you can blob pads together instead of using buss wire, for instance, without that potential problem.
FYI, I do over 95% of my soldering without feeding solderwire. And I happen to use the same iron.
I will suggest you look at the Hakko CF tips, the T18 CF3 in particular. And a bucket of flux. Using this tip, you touch it to the solder to pick a bead, and it stays on the tip. Then you touch it to the joint. I solder maybe a dozen small SMD passives without reloading; (it works for thru hole, too). Now that I see the 8803, my curiosity is piqued. I hope it works out of you. But in tighter spots, maybe you can get some use out of the CF tips, the way I do.
For reference, you can see a simple board I made the other day. Because it shows and because there's no soldermask, I bumped down to my CF2 and used it inverted to ensure neatness. No solderwire was directly handled, at all. Check the "other equipment" forum for the Hakko 888D thread.
