Can't comment on SH as I've never used them. I've just replaced a 3rd failed Raymarine 55e with an Icom 323, I had an Icom on the last boat for 6 years & it never missed a beat. Icom every time for me, I've learned my lesson. I have an Icom M71 handheld, no problems. I use Icom PMR handhelds at work, they've been dropped in deep water, onto concrete, covered in sh1t & never fail.
Rule#2: Never argue with an idiot. He'll drag you down to his level & then beat you with experience.
Rule#3: Tha' can't educate pork.
Rule#4: See rule#5
