What are the best meal prep containers that don’t leak or smell after a week?

Struggling to find containers that don’t end up smelling like last week’s curry or leaking in my bag. Glass seems ideal but heavy, plastic is light but sketchy. Anyone else dealing with this?

I’ve tried a bunch of random ones from Amazon and my local store, but most either crack, warp, or just refuse to wash clean. What’s the secret? What do you swear by?
