Which one should I use? VSL#3 or OTC probiotic?

I am currently using an OTC probiotic with 10 billion CFU's. (it is a blend of lactobacillus and bifidobacterium lactis)
At my last appointment my GI wrote me a prescription for VSL #3 because we thought it might be a less expensive option than the OTC probiotic. My cost for the prescription is higher than the OTC.
My question, Is the VSL#3 a better product? I am willing to pay more if it is worth it.

I will tell you my experience with probiotics. I tried 3 or 4 pretty expensive brands, gave each of them a fair shot of 3-4 weeks, and each time I got worse symptoms. I figured probiotics were not for me. Then a few years later, my GI practically insisted that I try Align, so I did. After the initial die off, it actually helped, I was shocked. But then about 8 months after that, the benefits were starting to slow down, I was getting some bloating and gas again. My GI told me that your body can get used to the strains in one brand and sometimes you have to switch it up for a while. So he recommended another brand, PB8. I now switch between the 2 and do OK. Sometimes, if things are really out of hand, I will take one in the AM and the other in the PM for a few days/weeks to get things back in line.

I think it really is individual, and if you have one that works for you why mess with it. It took me years to find one that helped me and I was ready to never try them again. If in the future, you find that you aren't getting the same benefit from the one you are taking, then try the VSL, but for now, why mess with something that is working?

I think I do fine with the ones I buy over the counter as I would with rx probiotics. JMHO
