I went with the PowerMaster XS mini-starter mainly because I was having issues with other mini starters not having the “reach” or “throw” that I needed with my PRW flywheel. The XS had the largest printed spec value I could find for pinion stick-out when comparing all the brands I could find with internal shims/spacers removed (not talking about the external mounting shims regarding tooth mesh).
The negative with the PowerMaster XS in my case revolves around the side they chose to mount the terminals on. No matter how I orient or clock it, those terminals are always on the outboard side of the engine facing my RA manifolds/down pipes. The higher end PowerMaster’s have the terminals facing rearward which I would prefer. The IMI appears to have the terminals on the inboard side facing the block/oil pan. That would be nice.
I ended up going with these for battery cables. I was more concerned with durability than OE appearance and loved these custom made ones in particular on other cars. Double jacketed and they still route more like welding leads than traditional battery cables.

I ordered Wednesday afternoon and they showed up to my house in NY Friday morning. Just throwing that out there because you mentioned cables!
