With such similarities between lavender and nepeta, I would go with the lavender. I've found that 'Munsted' and 'Hidcote' (best color) are excellent lavenders to use, loving the heat of summer as long as they have excellent drainage. I don't think you'd have any problems with them unless your experience proves otherwise.

Nepetas need to be cut back hard (at least half) to keep the flushes of blooms coming while lavenders don't. That said, they are nice to use, but I wouldn't look forward to climbing those walls to cut them back three times per year! Also, I've never had problems with our cats (three of them) getting into our plantings of nepeta. They seem to prefer it dried. Actually, our biggest cat is allergic to it....sneezes like mad when he gets near it!
