Yes, it's been a way better deal to go for a subscription than pay as you go for me in the past. I had a month where I burnt through ~3.8b tokens which was somewhere in the ballpark of $8k worth of savings.

Now though I don't dare use spend tokens for basic note taking with Sonnet because I'm hitting the limit over a couple million tokens on the 20x plan, so they've really tightened the purse strings since November.
