Flow is flow and good flow isn't always the right flow. Having a 40Br for almost 10 years, I've tried many... many different PHs. You name it, I've most likely tried it. I personally think people forget a difference aspect between the Vortech and other directional pumps. It takes less work, IMO, to situate a vortech correctly, than it does most other pumps. I would honestly say if you go with something outside the vortech world, and yet make the pump work well in the tank (As many others have), then great! You've saved money and can enjoy the hobby just fine.
After saying all of this I personally have two MP10's in my 40Br, and I absolutely love them. I wouldn't go back, but I understand your plight. I think Tunze's are great pumps as well. Prior to my Vortechs, I used the non-controllable Koralias.. and while it took many (A whole heck of a lot) tries to get their placing right, my tank chugged on just fine and happy. :)
