not much difference from what I can tell

Assuming you are Rank 1-3 and win 3/5 or accept and win 2/5: Per energy used on challenging opponent: 31 points Per energy used on accepting challenges: 28.5 points

Slightly more if going first but no risk of wasting your energy on bots decliners or shuffling.
