is ipad mini 7 overkill just for reading?

is an ipad mini 7 overkill just for reading manga/manwha?

i work from home and want to get into more reading

i do have some holidays lined up for next year

i currently have the original ipad m1 pro 11 inch ipad, not sure if i should stick with it or upgrade to the mini 7

or do i save money and buy the 6 instead which is about $300 less
