my skill level doesn't allow me to hold the proper angle and a lack of blade feel.
I feel like trying to solve skill-related problems with new razors can be a road to disappointment. Not to say you shouldn't get a new razor if you want one, and I agree that angle management can be more difficult with low exposure razors, but you should still try to work on improving your angle control because it will help you get a better shave from whatever razor you choose. Basically, new razors are fun, but they aren't a magic bullet.
Anyway. I like my Nodachi a lot. It's a little bit too efficient for me to use as a daily shaver. The deep BBS shaves I can achieve with it mean that after 24hrs I only have a bit of sandpaper stubble to work on, and I prefer that the razor has more to do when I come to shave. As with other aggressive razors, I feel like a 36hr gap between shaves is the sweet spot for me, but I can use it daily for shorter periods if necessary.
In terms of aggression and other razors discussed here:
R41: Did not like it at all. Too much blade chatter. Sold it.
Rocca: Didn't like the ratio of gap to exposure. Felt closer to a DE89 than an R41 to me in terms of efficiency, but not particularly smooth or pleasant to use. Like @Iridian I feel that it just did not stand out in any way and prefer my Gamechangers, Lupos and Tatara. Sold the Rocca.
Nodachi: Almost as efficient as the R41, but without the hideous blade chatter. Smooth and intuitive to use whilst being a grade A whisker whacker. The level of exposure means that the rigidity at the edge takes a little hit, but it's pretty much the best compromise between rigidity and high exposure that I have found in a razor so far. Obviously it costs significantly more than the other two, but for me it is also the significantly better shaver than either of them.
Contrary to what someone else has said, I would not get the Tatara plates and cap to use on another handle. The Tatara baseplates have a gap which the handles "lock" into for maximum structural rigidity. If you want a Tatara, get the full package.
FWIW I also use my Nodachi head on a Masamune handle.
