Everyone is different and I would say do what you find works best for you. Research support that a mixture of low and high rep ranges is the most optimal. Gear increases recovery rates but does not change the fundamentals. I would recommend a daily undulating peridoization routine to maximize both hypertrophy via volume, and strength via heavy loads. I usually keep my strength reps around 5 or less, and my hypertrophy reps between 8-12. I rest 3 min inbetween strength sets and 1.5min for hypertrophy sets.
