I'm using the 40V chainsaw from Harbor Freight for trimming. It has worked pretty well, but just small soft stuff. The 80V wasn't yet offered.
The 40V pole saw is slow (slower than the chain saw) but I find it useful for what it does.
These haven't broken yet, are newer than other plug-in electric saws I used until they broke.
Lots of plastic crap these days. I used to see it only in cheaper tools (40 to 45 years ago when I had a job doing repairs at a rental shop). The better brands had metal frames holding bearings and gears. I still have my Milwaukee and Bosch from back then.
If you have the money to spare, a cordless chainsaw could be useful for quick trims. With two batteries, might keep up with moderate workload.
Of course, if you use gas tools regularly then are more reliable. Lots of my stuff gums up with infrequent use, although some (Onan on a trencher, Briggs on a tiller) start up after years of disuse.
Harbor Freight buys their top quality tools from the same factories that supply our competitors. We cut out the middleman and pass the savings to you!
