Race Chip Ultimate vs. Burger Tuner Stage 1

I'm torn between the Race Chip and the BMS stage 1 tuner. Is there a huge difference between the two units? Does one deliver power more smoothly, more power overall, etc?

I've read through the different threads for the RaceChip and the BMS, but there have been no direct comparisons.
