Kind of ironic, I have both and they wear the exact same scopes as yours but mine are Savages. My HMR is a SS HB with thumbhole stock and my WSM is a SS HB that I put a Boyd's Pro Varmint stock on and had the action bed. I also shortened the barrel on both down to 20 inches when they got threaded and tuned the trigger up myself on both of them to were they are right at 2lbs.
My 17 WSM actually out shoots my HMR. Shooting sage rats inside of 100 yards, to be honest, I don't notice a great deal of difference but when I start stretching it out to 150 and beyond, the 17 WSM definitely has more splat factor.
The Savage Bmag certainly isn't without its quirks and I think the early skinny barrel guns soured a lot of people on them but the Ruger 77/17 WSM wasn't without its issues either and I think I heard Ruger is no longer making the 77/17 WSM but I'm not certain of that. I do know the Ruger cost almost double what the Savage does though.
I also have a CZ 527 Varmint in 17 Hornet and they are an outstanding little gun. The little CZ 527's just flat shoot and they are a top quality piece. They're still VERY quiet, not much louder than the HMR but downrange they deliver considerably more splat factor than the HMR. Depending on what your intended use is, I'd give a lot of thought to skipping past both the HMR and WSM and going straight to a CZ 527 17 Hornet.
