sr pros:
30-33mpg at 2800lbs
easy to work on
good mostly stock around 400rwhp
add pros now....

srcons:
first and second are always kind of desperate and more power makes the trans potentially suffer disaster as clutches get more "grabby" 500rwhp+
six speed version is slightly unreliable w/ circlip
automatic is not really an option
limited qty getting expensive

2j pros:
legendary 500-800rwhp stock block
auto version is acceptable
will work in heavy cars

2j cons:
expensive (turbo versions w/ low compression and piston oil squirts)
I heard its heavy
max mpg is 25-? (anybody have data @ 3000lbs?)
auto version is dangerous (no torque management has resulted with crashes).

ls V8 pros:
some cheap iron blocks are almost free and do 500-600rwhp with a valvespring and water injection turbo
the lighter, aluminum version supports even more 800rwhp and holds some kinda records (L33) still cheaper than a 2J and probably weighs less ("the new/next 2JZ")
Auto includes torque management factory for auto daily driver (ex. rain)

ls cons:
the light ones are expensive
the cheap ones are heavy
the best auto transmission 4l80e is so heavy inside it limits economy, at 3000lbs it may be low as 25mpg, depends on gearing
8 spark plugs now, can you reach them all?
Etc....

Ok now add all the ones I missed or fix the sentences so they are true (and then vote on a best engine based on pros and cons)
