I recently decided against a 1+10 Pro for a 9 Pro. Price was a factor, as was the fact that they are not massively different in capabilities. But the final nail in the coffin was alternative rom support. Both are not officially supported by Lineage (yet?). But there are inofficial builds for the 9. Apparently OnePlus stopped supporting some tool that is needed to safely develop roms without risking to brick the phone.
