"Both converters ranged on average between the low 1s with 1.25 frames being the low and 1.375 frames being the high. Now all these numbers may be a bit overwhelming and may sound confusing to you. Just know that through this testing it shows that the REAL converter is as consistent as the Pelican ones when it comes to inputs.
Ultimately, I have to pass the converter crown for fighting games to the REAL PS2/PS3 converter as it does everything the Pelican one does and more. Length wise they are about the same, and they also both have LED indicator lights as well as the much needed PS/Home button. One advantage the REAL converter has is that it supports vibration feature wheras the Pelican does not."
