Agree 100%, i have had a link in my 33 gtst for around 2 years and it's never skipped a beat.. it has tunability for all my mods (and future ones) and more, launch control is a great bonus, and laptop tuning and data logging was a big plus for me when deciding..
Don't know all the ins and outs for the PFC so i won't comment, they've been tried and tested and have seen awesome results on heaps of cars, i've also seen the same from link ECU's and thats what i have so my bias leans towards Link.
As with the prices, both the PFC and Link can be had for cheaper than your original prices, it's just a matter of looking around..
Cheers, ultimately it comes down what ever fits your needs best... good luck
