Yep, "comparable" :)
T4 must be the product of CS Chinese partners. There is also H4 by Amphenol company in Germany, and if you check Ebay, you'll also find "PV4 MC4" from nameless and countless Chinese factories. Unlike MC4, none of those is UL approved, and neither is mating MC4 with others. Though Amphenol took pains to test according TUV standards and submitted reports saying that H4 are fully compatible with MC4.
I guess you can plug it in.
"Better"? Who knows... Wouldn't bet my life on it.
Edit - PS:
it's always a good idea to tuck the connectors under the panel, away from rain and UV, be it original or "comparable".
