Yea I like my 350's... clam shells with a plastic case! But they work. BUT u can argue... Husky mid range saws are the pro cases with lesser filter/top ends like the 555's or simply plastic and a few detuned details like the365 vs. 372's..... Where clam shell over laps pro level designs is where many folks spend their money... that $500 dollar range. Does it matter? No, not really unless needing for a reaction on a place like this..
I have a 455 on the bench with crush/dropped from a bucket truck damage. The guy has used it in a pro logging environment since he bought it in 2005.... but to listen to many experts it's not a suitable saw for that role but there it is, still runs nice just gravity and 30ft put a hitch in it's git along. Obviously clam shell's have been performing well for a very long time. Just a Pita to work the cylinder for more compression. But who cares about that??
SO I have a 455 with a broken handle and mashed covers on the bench.... And the Sea Ray is right next to it and drawing my attention away from saws for a while...
