Foma films are good value full stop. Buying rebranded is not a good idea, as the batch numbering information is lost and you might be buying b-stock or old stock foma.
I am very bothered by defects and I'm very anal about my process and my results. I choose to use Foma and Ilford and overall I find that my failures are due 99.9% of the times to human error (mine) rather than issues with the media I've chosen to use.
I haven't used Kodak black and white film for many years and I honestly don't miss anything about it.
I'm glad you like using Foma films. So do I. I've used them for 15 years, both rebranded and original, and have found a larger amount of defects in them than I get from the big 3 manufacturers. But, I think I have a higher tolerance for these defects than most, and sometimes even enjoy them.
I think that buying rebranded is a good idea because I've been able to pick up fresh Foma for as little as $4 per roll in the past year, which is unprecedented at today's prices, and the performance was not any worse than buying original.
As far as Kodak B&W goes, I'd definitely miss anything in their -X line of films if it were no longer available. The others I can take or leave.
