I keep Lawry's around for occasional use; it's a grilling classic. Not familiar with Johnny's.
My most often-used seasoned salt is Herbamare (now renamed "Herbed Sea Salt"), an organic salt from A Vogel. It's more vegetable than herbal or spicy - flavors of leeks & celery, Has virtually replaced plain salt at my table for at least forty years. I still use plain salt for cooking, but for afterseasoning it's nearly always Herbamare. Unlike most seasoned salts it's capable of subtlety; enhancing tastes rather than remaking them the way a stronger flavor would.
Also made with an unusual process, not just herbs & spices mixed into salt. It's blended into a brine/broth then freeze-dried: every crystal contains the full flavor. Highly recommended.
I keep a shaker of Montreal steak seasoning handy also. Not just for steaks, but also potatoes, pastas, eggs - good on plain cottage cheese too.
