In my store, the TL writes reviews and submits them to their ETL, who reads and comments on them before the TL completes the "final" version which is gone over with the team members. Any raises would ultimately be the ETL's call because they are the ones responsible for the budget. Because you're ultimately quite involved in the review process even though you might not actually deliver the reviews, it will be of benefit to you to get to know all your TM's. Besides, you'll work more hours than your TLs anyway, so you'll see things they don't. In some cases, particularly if you were working dayside, you'll see them far more than the TL. I know some nighttime sales floor TMs only see their TL every four weeks on their closing weekend because they don't happen to work on their leaders' closing weeknight. In that case, an ETL who does work with them one weeknight a week might have a larger amount of input into a review than a TL, and understandably so.
Some ETLs work better with their TL's than others; I know that in my part of the store, the ETL intentionally had opposite weekends with a couple of his TLs who run departments the STL considers super important, thus providing some level of knowledgable supervision every weekend. Probably the most contradictory messages people get in the store is not from ETLs and TLs in the same area but when ETLs from other areas throw their weight around during LOD shifts. That doesn't happen too often at my location, but when the LOD says something needs to happen...well, you just do it.
