What has better resolution Sigma 120-400 or 150-500?

Which lens is sharper at 400mm? I hear that the 120-400mm is "generally" sharper than the 500mm sibling, but since I'm not necessarily concerned with 500mm I'm wondering if the longer lens would result in a better 400mm since its not extended all the way.

I have no experience with the 120-400 but I'm happy with the 150-500.

I have 120-400 for portrait outdoor use, actually both versions, and very content with it/them. Cheapest for the job between focal range 120-320, which is the best range of this lens. Very good OS for handheld.

I owned the previous HSM non-OS version of the 120-400 and was pleasantly surprised by its performance. A bit soft at the long end, but really not too bad at all. By all accounts, the 150-500 is very similar in build and optical quality.

I own the 150-500 its sharp but very slow make sure you test before purchasing there are some bad ones out there.
The lens can do the job pretty well as pic shows.
