There are certainly some differences. I worship in both and can only share my own experience. Note, I am an occasional pew warmer in an Episcopal church, not an expert or even a member.
In terms of worship experience, the Episcopal Church (ECUSA) is more centered on the Eucharist and the UMC is more centered on the Minister's message. Anglicans gather for Eucharist every week. Methodists' communion frequency varies, often only once a month
(I think the Anglicans may be on to something here. I have never been to a bad Eucharist, but I've heard many a poor sermon.)
My other observation (in my limited experience) is that ECUSA worship is more liturgical, more formal, and more reverential (my opinion) while UMC worship may more frequently found to be more contemporary. This observation may only reflect my bias, however, since I am a refugee from the informality of my UMC, and have found a "high church" Episcopal Church that I like to worship in.
Both ECUSA and UMC have open Communion.
I don't find lots of theological differences that cause problems for me. When I became disillusioned with my UMC and decided to visit other churches, I thought I'd start closest to the UMC's theological roots. Since we came from the Anglican's, I chose to start visiting there. It's been a good experience for me. I'm still a United Methodist, but I could easily be Anglican.
I would add that recent decisions of the church on the bodys' official stance about ordination of homosexual clergy are somewhat different in that the ECUSA will ordain practicing gay persons and the UMC will not--at least to this point. Within the body of believers, you will find all sort of opinions on this in both churches. Both churches are accepting of homosexual persons in the pew, in my experience. Both churches accept female clergy.
