Depends on combat level.
higher combat:
80 attack
99 strength
40 defence
44/52 prayer, or 95 pray.
-60 attack turm fails, for the most part. Cmaul+korasi+gs+rapier with smite > turm at 60 attack-
personally in the 84-90 combat range, rune rangers own it up:
50-60 attack
89-99 strength (depending on attack level)
42 defence
99 range
94 magic
44/74 pray
^acts as a great low level tank, as you can handcannon and rune cbow in full rune quite easily, as 99 range + rigour/eagle will easily hit through 45 defence. Also, lower constitution lets it act as a void rusher, which if you do well, is great cash.
for pures/low hybrids:
60/88
1 defence
45/52 pray
99 range/mage
low level brids are the most fun, nowadays these brid fights (popular at green drags) almost always include protection pray
for fun: low lv hybrid
cash: rune ranger (least expensive, at lower levels much higher chance to smite out low pray pures, and hc rushing = free claws)
the 80 attack turm accounts are simply amazing, rare to get smites, but they rape, like always
