From having owned an Optispark... and have driven and worked on enough HEI cars...
HEI
Pros: simple, easy to maintain, many upgrades available, durable and reliable.
Cons: older tech, but the aftermarket has fixed those weaknesses.
OptiSpark
Pros: More accuracy and precision in timing control
Cons: hard to maintain, problematic, costly, limited aftermarket support, can fail at higher RPM.

Humm, you sorta of get what you get!
LT-1 will come with Opti and L-98 HEI. I still like like the LT-1s even if it does have the opti spark.
