What is the quality of the MacBook Pro replacement battery?

The battery life on my Macbook Pro (15", mid-2014, retina) has decreased significantly over the past few years, from about 8 hours of charge to barely 2, and I want to replace it, but don't want to pay $200+ at the apple store.
How does the replacement battery ifixit sells compare to the original battery that my laptop came with? I could not find any mention of a brand- what manufacturer is it coming from?
Also, some repair shops have told me that the top case may also need to be replaced along with the battery. Is there any truth to this? Will replacing my battery damage the trackpad since the battery is glued in? Any suggestions on how to avoid damaging these other parts while replacing my battery?
