Some members have reported a big improvement with the Delco system. I suspect that they may have had a weak coil in their Magnavox system. When my son & I made the swap we didn't think it made much if any difference. It was my son'* car at the time & I really didn't drive it much after the swap, maybe some others will chime in.
The swap itself is easy to do. Here'* a link to the Techinfo article.

Yep, problem solved. When I pulled the negative battery cable from under the coil mounting bracket the other 2 grounds moved up out of sight. When the car wouldn't start I swiapped back to the Delco system & it still wouldn't fire up. The next morning I traced the ECM grounds back to the engine compartment & put 2 & 2 together.
