I want to know how many IP sessions it can handle, the VPN throughput and IPSec VPN peers. I am trying to compare it with the Cisco-ASA-5510 firewall

if that case 
go with ASA 
it is more powerful for VPN s2s and remote Access.
for NATing both are close similar.

Note:- the only points that make Router better than ASA for VPN is 
1- Router support DMVPN 
2- router support VPN that use dynamic IP not static IP
