experience = cousin owns an asvRC85, pre Terex, ive ran it a bit, rides great, runs great with teh perkins powerplant, no lack for anyting i needed at the time, I was grading, pushing, digging, not mulching
rented an SVL75-2, more rough to ride, short on power at times but manageable, sluggish/delayed hydraulics may have needed adjusting?
worked with SVL95-2 , contracted the guy with a turbo type saw to take down a couple acres of large trees - he had just traded up from a SVL90 and said it was significantly more feel of response/power and keeping saw running, he also has a mulcher and said he really noticed the difference keeping the drum spun up.
I will say concur, more maint on the ASV tracks as more moving parts, ASV went downhill when Terex was building but since they went back to their own company owned units and parted ways, from what i have heard the quality/build is much better
myself from running machines, you probably wouldnt notice 1gpm on normal work but 5gpm in hi-flow would be more noticed. The ASV has 200 more lbs of hydraulic pressure so that might help keep things spooled up a little better with the reduction in HP to keep things spun up, that is where the jewel lies, when it starts loading and the motor pulls down, it will take longer to spin things back up with the reduction in HP - the only way you could really know is drive one into the same pile of brush and TIME it and experience the lag.
mulching and hydraulic motors take some serious flow/hp to keep running, that is why they make things so heavy to keep their momentum, not to mention the 2300 lbs of weight difference, THAT is HUGE, when it comes to comfort and tossing you aroudn in there when lifting, lowering, tilting, moving, mulchers and mowers are HEAVY and will ROCK a machine and it wears on you.
I know what i would do but its not my money and you have to be satisified NOT ME - if its a budget thing, if you are just doing things for yourself, if you are not riding in it all day and in a hurry trying to make money, if someone else will be running it, etc.......all things to weigh in.
ASV makes a bigger machine too!!!
