I am very happy with my five ton electric splitter. I burn about seven cords a year. I cut on Saturdays, and then go out to the woods after work on weekdays to bring out rounds I cut over the weekend. Some evenings I go out and split a little while.
For the same price as my bought and paid for electric (with a two year warranty on it) I could have rented a gas powered splitter from Home Depot for I think two eight hour days. Maybe three days at eight hours each. Much easier on my back to do 30 minutes a day.
At 25 cents per kilowatt hour for electricity, splitting a cord costs me about 6 to 8 bucks max, and that is assuming 100% duty cycle on the motor. Real world, probably 3 or 4 bucks actual electrons sucked through the meter.
Yes I noodle stuff in the field bigger splitters could probably get through. Yes, the ram isn't very fast - but I am talking 7-10 cords per year, not per week.
OTOH clear rounds with no knots, or just a couple small knots, mine can pop a 20" diameter round without blowing the circuit breaker.
I had three brands to choose from in town, they all sure looked "the same" except for paint color. For me the Homelite one from Home-Depot was the least expensive one, I think I got the two year extended warranty (four years total) for about an extra $15.
If I can split 40 cords with the thing in the next four years I'll be out about $150-160 for electricity, have no payments on the splitter, and only have the one trip to Home-Depot to have bought the thing in the first place.
Not for everyone, but certainly worth a look if you have mostly pretty clear wood to split and are only splitting for yourself.
