re: workout splitter strength training: M/Tu/Th/Fri vs M/W/F ?

I’ve had great results with both, but prefer the 4-day as a matter of personal preference. Reason being is that 3-day splits feels like it pigeon holes me into full body workouts and I tend to overdo it or take too long for the workout with those. I don’t think either approach is inherently wrong and it’s just about what fits your schedule and what you’re trying to achieve.
