Don't you need to pay a ton to actually get your data out of glacier?

Not if you're willing to wait a few hours - a delay of the same or smaller order of magnitude as the transfer is going to take anyway.

For example, suppose you're restoring 50 GB. If you want to start the retrieval 4 hours from now (the minimum), you'll pay $97. If you're willing to wait 10 hours, that drops to $43. 20, $25. 40, $16. Goes down to $7 at the limit.

For me, the far more likely case would be 500GB, kept for a year. Even with 1000 hours (more than a month!!) for a restore, I'd still have to pay $125. CrashPlan lets me do this for free, and allows me arbitrary access to my backed up data to boot. It just seems like a better deal, unless you're really worried about data corruption in the cloud.
It's the same price for ~72h retrieval...
Still, it means your monthly price isn't actually what it seems. With 72 hour retrieval, you'll be paying about $14 a month, compared to CrashPlan's $5. And what if you need the data earlier? If you have bad luck and your hard drive crashes a month after you make your backup, you'll end up paying about $100 a month, at least for that month. CrashPlan's flat rate means you don't have to stress out about the fine print.
You have bigger problems if you need to recover from backup once a year.
Even at 5 years it still averages out to about $7 a month. CrashPlan is significantly cheaper, unless you want to bet against ever needing the backup. (Which may be sensible, I admit.)
That's ok. When that happens I'll gladly pay a premium to get my data fast. That should only happen once every few years though.
