Now that I know what you meant, I'll add that VPN server isn't something most people are looking for. I'd call it a fairly advanced feature. The G1100 is not targeted at super users. It is a very good, general purpose device for the majority of FiOS users. I woudn't call it "limited," just mainstream.
At $199, I do think it's overpriced as there are plenty of other routers at that price or below with more features. Verizon sometimes discounts it with certain bundles and/or speed tiers. They've had it on sale in the past. At lower prices or even free, it's a decent box for most people.
Since you're a super user, you probably don't want to bother with the Quantum. Stick with an Actiontec and put your router behind it. There's a good FAQ over on DSL Reports that describes the different ways to use a non-Verizon router and the trade-offs. If you don't have TV, you can simply switch your ONT to Ethernet WAN and then plug your router in (be sure to release your WAN IP before removing the Verizon router, or you'll have to wait two hours for it's lease to expire).
