I'm interested to know this as well. I guess it depends what you're shooting. Indoors, outdoors, the size and shape of the modifiers that you'll be using, if you need heat resistant modifiers, etc. The OCF speedring is lightweight and made of hard plastic so it can't handle the weight of larger modifiers. In your case, I would stick with RFI speedrings to be safe.
Yeah that's exactly what I ended up doing
This website shows a really good comparison as to how the RFI vs OCF speedrings work.

From what I understand, these are the critical things to know about the RFI vs OCF speedrings:
1) RFI modifiers will only work on RFI speedrings, and an OCF modifier only works with an OCF speedring. The rods are designed differently, and attach to the speedring differently. This is kind of an odd product design choice for us photographers I think, and they don't make it any easier to understand via their website.
2) OCF modifiers have fixed front diffusers and removable inner ones, whereas RFI modifiers have removable inner and front diffusers. Again, kind of flawed design approach in my opinion considering a lot of photographers like to experiment with different qualities of light from their expensive modifiers.
3) RFI speedring is much larger and heavier, which has obviously pros and cons as the RFI speedring is more durable
I decided to order a couple RFI modifiers, which partially dictated my choice. I also really dislike that you can't remove the front diffuser on the OCF modifiers. The modifier I use the most on location is a 3 ft octa as it's pretty easy for an assistant to hand hold, and that seems to be only available as an RFI modifier. It doesn't make sense for me to have an OCF and RFI 2x3 for different situations - I'd rather get the RFI one and know that I can use it for everything with perhaps a bit of a weight penalty.
