Dudes (hoosiers15 & Servo888),
You can mix-&-match as you like... experiment & see what feels good & what works well for you... you can do any & even all of those workout approaches, or take parts of each & make one you like.
The article discusses PROs & CONs, but some are pretty weak/contradictary, like mentioning that wimping-out & not completing a workout is a CON as is holding back energy in reserve (not giving a MAX effort for each exercise) in completing a workout: truth is that you're rarely -- if ever -- going to give a MAX effort on any given exercise in a workout & not hold back on another exercise, unless you do only 1 exercise each workout... & not one program mentioned had that philosophy. So guess what? You're going to hold back (so forget all about holding-back being a CON).
But not to worry, you can rotate exercises so that today's hold-off or slacker is tomorrow's go-for-broke. Reps & sets can be varied as well either each workout, or each week, or each month, or each new training program [you get the point? You're not locked into doing something that you're unable to do -- DO what you can that makes the most sense for you & in accordance to how your body responds... start with something easy for you & ease into your training & experimenting (& see how your body responds), as you can always add more (weight or reps or sets or exercises or whatever) next workout or work-schedule/routine IF you remain un-injured; but if you jump-in with too much workload too soon, then you risk injury, you'll probably be in great pain, & you may just quit altogether, or be faced with a long lay-off period which are both truly CONs].
And another thing: a truly MAX-effort is dangerous (as it's on the borderline of killing or injuring you, else it really isn't a MAX-effort). The 1st Marathon runner gave a truly MAX-effort: he completed the run & then died.
So DO something that's within your capacity to do that doesn't waste your energy reserves. For example, if you liked the old-school muscle-pumping program but can't do beau-coup sets, then scale it down & do fewer sets of 8-12 reps (& if you like, have periods/workouts where you do less reps, or more reps, & heavier or lighter weights -- as you see fit).
The aim of your experiments is to find one or more ways that work well for you (you might pick a winner right away, & you might not); you'll need to seek ways that balance (appropriate amounts of) EXERCISE, NUTRITION, & REST; & with exercise routines you need to find balances between many factors such as POUNDAGES, FORM, REPS, REP-SPEED, PAUSE-or-NO-PAUSE-BETWEEN-REPS, SETS, REST-BETWEEN-SETS, TOTAL-WORKOUT-DURATION, REST-BETWEEN-WORKOUTS, ROTATION/CHANGE-OF-EXERCISES & VACATIONS/TRAINING-BREAKS (& every injury/disability will have with it another set of variables to consider).
There really are many ways to skin a cat -- so start skinning & see what works (& keep an eye out for other methods).
The most useful saying I believe the late Bruce Lee uttered was something like, "Absorb what is useful." I didn't absorb his other sayings... hmmm... (c;
P.S.: I believe that a good start involves using light to moderately-light weights & slightly-slow reps as you'll feel the muscles being exercised during the set in a safe way, & your muscles will be working the whole distance of each rep, unlike fast, ballistic-style reps where form often takes a back-seat for the sake of increased poundages & the muscles actually relax during the weight's momentum-driven flight on each rep (but this way is a decent way for developing functional power, so you may want to do it from time-to-time later in your training).
