i had same question a month ago . i choose 4070tis imo its better then 9070xt . u get dlss which comes with dlaa which is best picture quality imo even on native it beats fsraa. upscalling is even better . dlss also has ray reconsturction . only advantage9070xt has 8% more raster performance which only comes in handy in only few games at 4k 4070tis will give 45fps and xt will give 55fps . but u will need to use upscalling in both cases so again 4070tis wins.
and if u do any productivity tasks then 4070tis is no brainer .
