You can't really compare the ME3600X/3800X to the Juniper 
EX3200/4200 switches.

The Cisco options are more routers than switches (even more 
routers than switches when compared to other Cisco switches, 
including the older generation ME switches and the newer 
generation desktop switches from Cisco).

What this means is:

	- You'll get better IPv6 support.
	- You'll get better filtering support.
	- You'll get router-like QoS support.
	- You'll get EVC support.
	- You'll get full MPLS support (including TE).
	- You'll get MEF-type support for Ethernet.
	- You won't lose typical Layer 2 features.

The main difference between the ME3600X and ME3800X is 
scale. 

The ME3800X is positioned as an aggregation device, while 
the ME600X as an access device. All this means is that the 
number of ACL, IPv4, IPv6, Multicast, MAC address, bridge 
domain, e.t.c., entries will be slightly higher on the 
ME3800X than the ME3600X. Apart from that, all other 
features are the same.

I feel the ME3800X would be useful as an aggregation device 
if you're looking at high volume, low cost aggregation 
solutions for situations like LTE (where the MX and ASR9000 
are great, but just too big/costly). Otherwise, for the 
majority of cases, the ME3600X is fine with me, since for 
me, the platform is the ideal solution for MPLS in the 
access, and getting rid of STP and all that nonesense once 
and for all, when building large scale Metro-E access 
networks.

Hope this helps.

Cheers,

Mark.
