Please read the Hardware Sizing guide, found one click from the pfSense home page and search this forum. There are many threads on sizing and there's little point in re-hashing them ;)
51-200 Mbps - No less than 1.0 GHz CPU
201-500 Mbps - server class hardware with PCI-X or PCI-e network adapters, or newer desktop hardware with PCI-e network adapters. No less than 2.0 GHz CPU.
That rules out both your choices (BTW, did you read the product description page for that first one? The one where it clearly says it can't push more than 85 Mb/s?).
Two key things to note:
You'll never achieve 100% bandwidth usage. If you need 200 Mb/s of throughput you'll either need to aggregate 3 x 100 Mb/s ports, or use a Gbit port.
Packets per second usually matters more than raw bandwidth usage (more details in previous posts).
