OK, trying to keep up here but struggling.
So which is the top option between the V-1710-E27 and the V-1710-H?
And photos would help please...

A power recovery turbine setup, like the E27, is best for raw power at medium and low altitudes as there is no need to throttle the turbine. A pure turbo-supercharged engine, like the V1710-H, is a mechanicaly simpler and lighter system that offers better fuel efficiency at a slight cost in maximum power
Seversky XP-41 has no place in a turbocharged list. The engine is Pratt & Whitney R-1830-19, a two-stage gear-driven supercharger with an intercooler between the stages, a close relative to the engine used on the F4F-3/4 and FM-1 Wildcats.
The XP-41 is quite well documented in the NACA series reports (e.g. NACA WR E-105)

Unfortunately there is a lot of confusion about the XP-41. I believe there were two different Seversky fighters built for the 1939 fighter trials, not sure if they both showed up in time? One had the two stage mechanical supercharger, as you describe. The other had a turbo (the AP-4) and was a company owned demonstrator. The problems seem to be which airplane was identified as what later on. While rather similar (both had the inward retracting landing gear) the air scoops/inlets in the wing leading edges were different.
A lot of books/articles seem to confuse the two planes and often misidentify photos.
The XP-41 had a carburetor scoop above the cowling and unique flush folding landing gear unlike any other P-35 derivative. It definitely lacked a turbo and may have only been a single-stage setup.
In the same vain, the Curtiss model 75R is often claimed to have a two-stage supercharger but in fact was equipped with a turbo. The typical photos in most sources are mislabeled model 75S pictures. This was the actual two-stage model.

Can you add a thing or two about this interesting aircraft and it's S/C?

Well, a lot of confusion was created over time but there was only one airframe officially designated XP-41, USAAC serial 36-430, the very last aircraft from the original P-35 production batch (36-354/429).
Republic turbocharged developments went on with the YP-43 / P-43 / P-43A series and the P-44 project.
