Hi Adam,
I can tell you what Gillettes work best for me, but it may not be the same in your case. Strangely enough, the various types don't perform or fit the same, so you gotta try em yourself. Heh, you probably knew that anyway.
If you like a little more bite, then go with an open comb. Some of those aren't much more aggressive than a straight bar, but others are a lot more.
Most popular Gillette models are the superspeeds, Techs, and adjustables. Pick one that looks good and give it a try for a while, and then sample the others at some point. That's the only way you'll find the right ones.
Most Gillettes will give me a good to very good shave. A few have too much bite, but most of em are set about the same on the Gillette adjustable scale (around 5-6). It doesn't mean they all shave the same though, because they sure don't. I can use some of those and get a very good shave, and those are my change of pace razors. There's only one model though that is an exact perfect fit, and that's the go to regular tool of choice.
Right now I have a few too many razors and would possibly sell a couple. You're welcome to use the pm feature if you have a particular type in mind, and maybe I have one laying around the arsenal.
Good luck with that particularly nasty rabbit hole you're about to slide down,
Martin
