LOR from professor w/ TA consult

I am thinking of getting an LOR for a professor with whom I've had moderate contact. However, I have had a very high amount of contact with the TA for the class I had the professor for (if that makes sense). How strong would the letter be if the professor wrote me the LOR but the professor consulted the TA and inside the LOR the professor subtly states that he/she consulted the TA?
