Think about what your using the car for, then buy ECU to suit.
The more advanced ECU's like Motec ECU are designed to work with high reving drag engines with 40 or so rpm rows. Link, Vipec are limited to around 20 rpm rows and Reytec to 16 rpm rows (same as stock ECU), PowerFC with 20 rpm rows. With Motec ECU + additional parts you can monitor shock rebound, upgrade to a more powerful ignition system, run fly by wire to replace TPS, on board datalogging, crank CAS setup, etc, hence why they are popular on racecars, high hp dragcars, etc. But they cost alot of $$$$.
Best bang for $$$ is Link, Vipec with onboard boost control (saves buying a boost controller), barometric compensation for changes in altitude (without additional sensors), IAT sensor for changes in inlet temperature (hot day, cold night), additional parts like knock block for knock control (bad gas), additional inputs, outputs, motorsport features (antilag, etc), datalogging, etc.
