Push pull training it twice a week is good as is Upper/ lower in addition to ICF5x5, SS and SL, Candito etc (I'm talking about routines in general.. SS and SL are much more specific to strength only training)
Problem is programming. Most people have no idea of programming... none. Hence why people do 8-10 reps for 4-5 sets. And then wonder why adding weight to the bar is nigh on impossible and hence make little progress for years. (Diet also a joint leading culprits for the mass of captain no gainers)
Doing a set programme with clear progression and thousands of proven results is the wise decision.
Push pull legs really requires you to train 6x a week to actually progress and unless you're a god of programming you'll go through periods of being overtrained (inb4 no you're wrong)
Also a problem of UL, PP and PPL is shoulder work, specifically pressing, pressing before or after benching? - ain't no-one getting good maximal volume into there press after benching and vice versa.
Yeah you probably don't need to bench or press for hypertrophy, but it's wise.
There is the argument that a noob can do whatever to progress but it's a flawed logic - why do something that might give you gains for a while but to
final point - 8-10 rep range is not wise. Most bodybuilders work in between 5 and 12. Even the super enchanced Ronnie Coleman did sets of 5, (there's a vid of him doing T bar rows for 5 and he was originally a powerlifter).
I've probably russled some jimmies and people are free to disagree with any of the above.
At least to start with people should run a decent programme.
