Which between Packet Tracer and gns3 is better suited for simulating MPLS vpn?

It better to use GNS3 as it is Professional / Expert level simulator

GNS3 is much better and if you want to simulate mpls vpn and more you can use web IOU

GNS3 can simulate MPLS vpn, but Packet Tracer cannot

GNS3 is the best and cheapest option to simulate most complex networks.

GNS3 because it simulates like the real router 

PacketTracer is a simulator with limited commands supported, whereas GNS3 emulates the real IOS. So i would say GNS3. 

GNS3

GNS3 is good but it stop working sometimes b/w your practice lab,  its better to use Dynagen(Dynamips)! 

For every advance router configuration GNS3 is better......But now the new tool UNL is best

GNS 3.2 is much more Better and its a professional while Packet tracer have Limited work to do    

GNS3 is the most best practice for MPLS VPN
