I owned a 7004 and auditioned SR-4023 with Focals, PSB. At any scale 7004 will be better than 4023. But when it comes to paying double the amount I will go for 4023. If you have big room go for 7004.
Loudness,
9' O clock position of 7004 >= 10' O clock position of 4023
Convenience,
7004 Manual controls for Bass, treble & Mid
4023 you can control Bass and treble from remote.
If you do not have the habit of changing gears in every 2 years go for the best ie, 7004
If money is a constraint then go for 4023 from hifimart.
