As I said, please compare the results between this variation and UNION ALL (or just UNION) variation. I expect it would yield different results in each case - you need to determine which logic is closer to your requirements.

As for speed, I expect that UNION version will perform with the same speed or may be even faster, but I would appreciate your test cases results, if you can post them here.
