Maybe...you will never have to replace or adjust points or condenser again. For a twin, that means that a $180 EI will pay for itself in about 9 years if you ride 10K miles/year. (points, condensers are about $10 ea.)
Only as reliable as your charging system, battery and your wiring. EI's are much more sensitive here.
do they add any performance?
No, but they do tend to have a better advance curve for BSA's than the stock points. Heavy duty advance springs seem to correct this if you want to stick with points...unfortunately, they've been hard to get of late.
what brands are out there it's for a 70 lightning
Pazon, Sparx, Boyer...there may be others. They seem, for all intents and purposes comparable, though the Pazon uses the newest tooling the Boyers starting to show its age a little bit.
Hope that helps.
Remember, the advice is free - weigh it accordingly.

IF your points and the AA unit are in good order and you don't do lots of miles or very high revs then there is marginal benefit. However if you AA unit is shot ( and most are by now ) then it is a no brainer to go for the EI units which are about 1.5 to 3 times the price of replacing the AA unit ( f you can find a good one ).
It is worth while to take the opertunity to do a rewire as the wiring is probably toast by now as well and if you go EI with existing wiring problems then expect to do a lot of pushing.

Hmmm ... while I've no experience of the Pazon, the reports I've read on here are positive, but so they ought to be for the cost.
Boyer-Bransden I've many years experience of - only B-B that's worth the money is a free one.
Everything else Sparx I've got has one quality-control problem or another; on that basis, their e.i. is too expensive.
The one you don't mention is Trispark. Steve's an electronics engineer, started out making e.i. for triples (he's a T160 owner) - do a search on the Triples On Line Forum and check out his feedback. His e.i. for a twin is a slightly different design but, given how long it's been out already, I don't see any reason to think it isn't just as good.
If I was paying my money now, Trispark is the one I'd go for, no question.
Interesting. Only ever had Boyers or Ritas. Ritas gave zero problems but were very expensive. Early Boyers had a problem with the anchorage of the pick up leads to the pick up coils but they seem to have fixed that. The only other problem is the crimp connectors which are too big for the cable and the solution is to cut off all of them and fit proper size ones after which all that I know of will give good service for a very long while ( I have an old red box one that still works fine, The down side is that the battery & charging side must be in good nick.
Don't get me wrong - I've had a Rita on my first T160 since it was about six months old in 1978 (fitted at the 3,000-mile service) and the second one had a Rita fitted when I got it at about five years old in 1982. Here in GB, Rita was only ever a bit more expensive for a T160 'cos B-B would use the standard 6V coils whereas Lucas supplied proper 4V coils; any other triple, or any Triumph or BSA twin, both would need new coils so any price differential was small.
My B-B experience is mainly sorting out other peoples'; I do have one on my T100 and, thus far, it's been ok. However, the only reason I'm using it is it was free and, if it gives any trouble it'll be off.
I'd go for another Rita if I couldn't have a Trispark but, in fairness, sourcing an amp. (the only bit that isn't available new), which might or might not need fixing, which might or might not need to go to GB to be fixed, is a faff few people would want. That's the reason I didn't mention Rita in my previous post.

To a great extent, same with a Rita, ime. But it's never caused me a problem 'cos I'm not surprised when something electric marked '12V' doesn't work at a lower voltage.
It's perhaps worth mentioning that, although Steve wouldn't recommend running either Trispark for any length of time with less than 12V, he did specifically build in a degree of low-voltage tolerance.
