My favourite is Ehiem (trust worthy) but the others seem to be more competitive in terms of watt used, esp Rio.
A few good pumps to compare (at 0 head loss):
Ehiem 1262 - 3400 l/h - 80w
Ehiem 1264 - 4500 l/h - 100w
AB 3000 - 3000 l/h - 45w
AB 5000 - 5000 l/h - 75w
Rio HF12 - 3000 l/h - 35w
Rio HF14 - 3500 l/h - 40w
Rio HF17 - 4500 l/h - 45w
Rio HF20 - 5400 l/h - 50w
