The 572 would be my choice. Stouter crank, bearings and oiler will always last longer than the lighter offerings and you'll never want for more cc's. Husky has also done us right by making them a cost-efficient rebuild should the need arise....
Starting @12:00 for 562/572 camparison and hot start issue solution.

Run fresh ethanol-free fuel, good oil (Love the clean burning Tanaka, non-synthetic), keep air filter clean so the wood fines don't get into the crank bearings, service the carb every few years for the same reason, keep the clutch/crank roller bearings lubed and the power head should eat up untold numbers of bars and chain. Still running the piss outta my father's half-century old Jony 52, waiting for the day I can upgrade but she still makes chips fly and me smile!
Pro Tip: Buy a Dualco grease gun ($18 on Bezo's World) for the bar nose roller/clutch roller bearings, drill and tap the thickest part of its cap at about 45 degrees from TDC for a zerk fitting so you can refill it with moly grease from your big automotive grease gun without the mess of unscrewing the top and ladling in the goop. Also, have your dealer remove/plug the compression release to gain an extra half HP or so. If you can't start the saw w/o one, go sit on the JV bench....
