I agree completely. Also I know that some brands are more prone to leakage, such as dreaded ELNAs, but I have yet to see a Nichicon to leak. But anything is possible, I also had a new Sanyo cap a few years ago that just bulged after few seconds.

A month ago I got an old tube radio from 1949 which saw almost no use since the 1955 or so, since all of the components were original and in almost brand new condition. After giving an hour or so for the electrolytics to revive, the radio played well. Actually that well and without any hum, that I decided to leave it all-original for now. I only needed to replace one tar sealed paper capacitor which got hot after few minutes and started to leak tar, others were perfectly fine. So sometimes even after 65 years, the capacitors work fine
