Blaster or Defender solo
Well, there's not really going to be a huge amount of difference. Kin is an offensive buff set, so it can make a Defender play very much like a Blaster. I would say that the damage is probably not going to be a big difference.
The Blaster will have melee attacks, of course. Electric's fairly good for Blapping, from what I understand, not quite Energy, but close. Thunder Strike is quite cool, too. Electric's End drains can give some of it back to you, so that helps keep End costs down. And Tesla Cage is probably the best power in both sets, you can just hold down a foe, close to melee and either Havok Punch or Thunder Strike him.
The Defender will have a heal with Transfusion, and the ability to really drain End with Short Circuit. Since Transfusion is melee only, you will probably want to stay near melee range even though you won't have nearly as much damage in melee. You can pick up a Power Pool attack if you'd like a little supplemental melee damage, though. You certainly will be using Siphon Power a lot (it makes a great pulling tool, as well as boosting your damage, and it stacks, so it helps to slot it for recharge) and once you get Fulcrum Shift you should both have a whole lot of damage, and some defense since you'll be debuffing your foes' damage. Between the heal and the damage debuffs you'll be less fragile than the Blaster, but not as much as say Rad or Dark would make you. You'll have speed, Endurance and firepower, though, so Kin's certainly a great choice.
ID and Speed Boost will be useful to you if you plan to solo, but you can always skip those powers. (or put them in a second build) And the powers that do effect you will do a really great job solo. Personally, I've played Kin a couple of times, and while it's quite powerful, in some ways it bores me. I think my problem was that I didn't want to go the massive End drain route, I was looking for something else, and that's not the best way to run a Kin/Elec. If that sounds like your concept, though, go for it.
The Epics I can't really go into, I've got a few characters in the 40's, but none with Electric. I do know that cone that Blasters get, Static Discharge, is quite cool, I've got the Dominator version of that, and it does a good job of making up for Electric not having a cone normally. I'm guessing Thunder Strike is quite good for Defenders, for all the reasons it's good for Blasters. Especially if you are going to be in melee anyway.
Go with the Blaster if you want to actually get through missions in a timely manner. You'll be defeated more often, but you'll move through enemies so fast that won't slow you down in the long run. Once the Blaster gets his APP, it's no contest.
Defenders don't even get an Inherent solo. It's no contest at all.

Elec has better melee than /nrg
I've taken both to 50, soloing much of the time.
The Blaster will be much easier to begin with.
Kin/Elec is a good Defender combo, high risk, good damage and not too team dependent, but it really takes a while to find its feet. Tesla Cage is at 28, Transference at 26. These are your two main pre-emptive damage mitigation powers with Transfusion patching you up as you go.
As an Elec/Elec Blaster you dont have great ranged burst damage, but you get Tesla Cage at 18 for pre-emptive mezzing of any mezzers and some serious melee firepower to finish what you started. End Drain becomes a viable tactic much later, but from your teens you can deal with most solo groups quickly by sniping one, caging the next and then just taking down the third member quickly with your damage.
If you do team every now and then, the Defender is better, but be prepared to slog it out until the mid 20s using Siphon Speed and jousting to stay alive in the meantime if you choose that path.
I'm having a hard time choosing between an Elec/Elec/Elec Blaster and a Kin/Elec/Elec Defender for soloing.
What are the pros and cons of both?
