I know it has been discussed all over the web and even in this forum ,main point is that these cameras are in a different league .If you shoot concerts ,stage events and don't have money for a full frame D700 or even D3s than the D300 is the best alternative in APSC. I never shoot Jpeg only RAW so let's see :
K7-12 bit RAW
D300s- 14 bit RAW (a lot of useful information to get in RAW ,blown highlights...)
K7-Flash X-Sync: 1/180 sec
D300s- Flash X-Sync: 1/250 sec (up to 1/320 sec with reduced GN)
k7-77- metering-segment sensor (coupled with lens and AF information)
D300s-metering-TTL full-aperture exposure metering using 1005-pixel RGB sensor
K7-autofocus -11-point TTL Phase Difference detection sensor (SAFOX VIII+)
D300s-51 focus points (15 cross-type sensors)
K7-speed-5 fp/s
D300s-speed 7 fp/s
and ... a lot more color noise for the K7 when shooting RAW starting with ISO 1600
If you want similar image quality to the D300s at high ISO buy a Pentax KX ,in RAW image quality is the same (very close Sony Exmor sensor)

Hope i am not intruding as i am a Pentax user for one week (bought a K-x for my wife for Christmas together with a Sigma 18-125mm F3.8-5.6 HSM) but i own a Nikon D300 that i use since it came out with Tamron 17-50mm (2.8) + Sigma 50-150mm (2.8) .I shoot only RAW with the
D300 and process with DCRAW or PerfectRaw mostly Concerts + Sport on a semi pro level. I already adore the K-x as i almost can't tell the difference on the pixel level between the pictures taken with the Nikon and the K-x ,both shot in RAW and processed the same way.(o.k i shoot 14 bit NEF's on the Nikon and probably 12 bit DNG'S on the Pentax)Agree the sensors must be very close.Nothing scientifical just everyday practice ,no Imatest or DXO.I am waiting to buy good Pentax glass to put on the K-x !
