I am certainly not in a position to say which one is best. The Husqvarna 338xpt that is now available as a Jonsorend 2139 seems to have the best anti vibe design. The Husqvarna 540t also has some effort put into the anti vibe. Is there anything else that is not basically the handles isolated from the rest. The battery electric has no anti vibe and is truly variable speed without the manual telling you to only use it full speed. This can be more precise in my experience.
I do not climb or work out of a bucket truck. I have worked out of a man lift for take down and chose a pole saw and a rear handle. The tree work I see the top handle fills a very small amount of cutting between a hydraulic pole saw and a rear handle. I have not watched orchard pruning.
What is best is subjective to the application. In the grand scheme of running an arborist business the cost of a top handle saw most likely is pretty small.
