Hi Nehmaan,
Sorry, previous my answer is for IOS routers.
Probably the answer to your question is below.
SE:
Cisco IOS Software functionality and hardware for mid-range and low-end Ethernet LAN switching for enterprise access and distribution networks, and mid-range and low-end metro Ethernet for service provider edge networks.
E:
Targets at enterprise core and SP edge networks. Supports advanced QoS, voice, security, and fixes defects.

Hi Yoichi,
I believe your latest email is more accurate for IOS-XE, Also looking at Cisco's Feature Navigator the "E" version supports features like 802.1q tunneling where as the "SE" doesn't.
Really appreciate it. :-)
Cheers,
Nehmaan
