A very young man (just turned 18) who works as a part time tech at a local audio shop, has done repair/refurbishing of hundreds of pieces of gear. He mentioned certain brands of caps that almost never go bad and others that he automatically replaces even if they look okay and have an acceptable ESR because he knows they will go bad in the future. He particularly does not like certain Panasonic electrolytics (grey in color) because they almost always end up leaking and the electrolyte is very caustic and destroys board traces when they leak. I just saw a Technics 1500 tape deck he worked on that he replaced 234 of these bad caps; it took him five hours (it would take me five years). Most of the caps he pulled did show signs of just beginning to leak. The owner of the deck is very lucky because there was no big leak damaging a board.

One of my favorite nerd-channels posted this today. It’s about millions of faulty and/or counterfeit capacitors flooding the market in 2002 and after. If you have gear from that era, you might want to check it out.
