For me, yes.
- The VPN is decent enough. The new linux app is decent enough as well. The best privacy-respecting VPNs are $5 a month anyway.
- Mail is great, Calendar is solid and great for my needs. Though I would much prefer calendar integration with Thunderbird.
- Drive is new and underbaked, but it is improving. Once it gets a Linux client and Auto photo upload I'll be happy.
- Proton Pass is solid and I like having passwords and 2FA wrapped into one.
I am also grandfathered in for the $6.60/month for 24 months plan. For that price and combination of services (And even at $8/month) it cannot be beat.
Too bad the development speed makes a snail look fast
