For most curries, the consensus seems to be pretty clear - make your own. I've tried pretty much all the Patak's varieties in the past, and the results don't compare to 99% of the material on this site.
That said, Pataks seems to be a popular choice for Tikka marinades - for many BIR's as well it seems. The Tikka and Tandoori varieties primarily. I have a healthy supply of both, and use them exclusively for Tikka marinades. For a great one, try Blade1212's tikka under the "Tandoori and Tikka" section.
