Hi Manda,
I love my R2 (aluminum) with Atlas handle very much.
It can almost provide me DFS with one pass+.
Could H2 be more efficient than SSH1?
When I know the classic version would retire soon,
I am on the fence if I should get M2 and H2.
I think M1 is surely too mild for me.
R2 is quite efficient and comfortable, but it still needs some care.
M2 seems to be a victor in providing care-free shave.
I appreciate your inputs very much.
Vincent - hey! I haven't forgotten about you. I wanted to mull over your question & make sure I give you a comprehensive answer. First things first - the H2 & SSH1 have the same blade gap, so in terms of efficiency, they should be about the same. The primary difference is the blade *feel,* and the fact that the open comb allows for shaving a longer beard with less clogging than the rinse ports on the SSH1 might allow. I'd say if you like the blade feel of the R2, stick with the open comb. The SSH1 has a smoother shave with less chatter and blade feel than the Classic open combs. Still very efficient, as the guys can confirm. But if blade feel is your jam, the Windsor has less of that. (Fun fact: Windsor open combs are coming! They're up next, after we get the new intermediate Windsor base plates up & running.)
If you find that you're having to exercise more care in your shave due to the aggressiveness of the R2, then the milder M2 might be the right fit.
However, if you're looking for a more efficient shave with fewer passes, I'd go with the H2. The type of soap or cream you're using could come into play here, as well.
What is your ultimate end goal? (Of course, you could get the best of all the shaving worlds with the full Classic Open Comb collection, but if you don't want to spring for both the M2 and H2, then determining your primary goal for your shaves, combined with what you already have, would be the best way to arrive at the best fit for you.) I hope this helps! If you have further questions, feel free to hit me up via email through the website.
