Depends on your pricepoint. MP10 (imo) is worth the price and although the WP25 specs are insane for it's price point (especially with the group buy!) there is nothing like a Vortech. It is the lowest profile powerhead thanks to the magnetic wet/dry side feature.
It's like getting a macbook or something. You can get another laptop just as powerful for way cheaper, but nothing has the exact apple feel or the proprietary software.
