Hi would like to ask between QQQ vs QQQM which is better if my intention is to invest and hold
for like 20-30 years?
I did some research and below are the findings:

Pros of QQQM:
-lower expense ratio at 0.15 compared to 0.20 for QQQ
-comparable performance to QQQ
-tracks almost similarly to QQQ(negligible differences)

Cons of QQQM:
-introduced in year 2022 which means still quite new with less volume and higher spread cost.
-it might be merged with QQQ or terminated in future
-unsure of future performance

If i am not planning to do options /trading should I go with QQQM? Since it is quite new
But would the future performance be a concern since both ETFs tracks similar holdings?
