I finally joined the electric crew when we lost our glow site. I still fly both.

Here are the advantages to electric:
I walk 1 block away and fly in soccer field.
No glow mess.
Support equipment in one small box.
Planes are small and can travel well.
Quiet.
No glow engine "tuning"

Advantage to glow:
Power -vs- weight is outstanding.
Cheaper - generally.
Love it when my SE goes straight up till it's a speck.
Much easier to determine power options and many more options seem to exist.

I would not start with a SE as your first electric conversion. It is an expensive setup. By the way I have seen an electric SE that will do everything a glow will for about 6-7 minute flights. However that is with a $200 brushless motor $100 esc and more $$ in batteries and charger.
I fly a couple of small planes - Herr Cloud ranger and 1/2a Lanier Shrike (fast). I have $10 motors and $30 esc's in them and they both fly great! I now get 10x the stick time I did flying glow alone - simply due to the fact I can fly them 2 minutes from home. My new glow field is 40Mins round trip. Performance on both of these planes is 70-80% that of glow. Not bad...
