Which Powerheads are considered "the Best"?

I have a 75 gal, standard size and was considering 2 seio 800 series.
im currently using 4 aqua clear 201

Try to imagine 30 tons of water being displaced every 5 seconds or so... (a SMALL wave in comparison to the big picture), then think of what goes on in our tanks... the powerheads being referred to offer very different flow patterns - the Maxijets almost straight sheer flow, which wouldn't be good if pointed directly at ANY coral. Seio's & Tunze's offer a wider sweeping swirling vortex kind of flow aimed more at volume than being directional, a much more natural "current" solution.

As for the money, you get what you paid for... period, the end. Maxijets are a good value for the $$$ and you can run them on a wavemaker. Seio's move way more water (read FEWER ph's = MORE flow), in a very natural way, again are good value for what they cost but you can't use them on a wavemaker.

Tunze - well, I already said it, you pay, but wow... With a six foot tank, they're not too obtrusive, and they are remarkable in what they do. Instead of just steady laminar flow or back & forth like with a wavemaker, these amazing powerheads make my reef come alive. I will have flowing motion one minute, then a gentle pulsing the next before a new flow pattern emerges. Every portion of the tank gets "sloshed" with a good current, and I couldn't imagine being without now. The ones I have are controlled and variable speed, (6100), but there are cheaper ones. Pro's - they're simple, easy to install and provide amazing natural water flow. Cons - Price of course, maybe a little on the big side but something this good has to be built right as well at the prices.
