The max is still an effective Lockpicking skill of 135, but IIRC there are only 1 or 2 containers in the entire game that require 135 Lockpicking, and both are in Deep Caverns. I don't recall either of them containing anything noteworthy whatsoever. I've found that an effective of 100 (or 85 if you have the Huxkey) is more than enough to get me everything I care about. Anything more than that is just a waste of skill-points, if you ask me.
The same goes for Hacking. The max is still 135, but there are only a few containers that require that much, and none of them have anything worthwhile. The only good reason to ever get up to 135 hacking is for that sweet Deep Caverns lore from IRIS, which honestly isn't that interesting and IMO is not worth the skill-points. She basically just tells you stuff you can already figure out yourself. I think the console in Oculus requires something like 115 Hacking (don't quote me on that), so that's as far as I'd ever go.
If you have to choose between the two, choose Hacking.
