I think the brands OCZ, OWC, and Crucial are a little out there when it comes to modesty and reliability. For that reason I recommend Samsung and Intel drives, which are good, come from huge manufacturers, and mate very well with Mac hardware. The SATA chipsets in Mac computers are made by Intel and the SSDs the Apple uses are frequently Samsung. Those two seem to be the most compatible. A lot of people choose OCZ and Crucial and they get them to work most of the time. They are certainly legitimate options.
It matters less the brand of the SSD and more the brand of the controller chip inside the SSD.
OCZ "top end" SSDs and OWC's SSDs use the first and second generation Sandforce controllers. These are highly regarded as the fastest and least dependent on TRIM as they do on-the-fly compression in order to lower the amount of data actually written to the NAND chips.
Intel makes their own controller for the G2, and then recycled it for the 320 series. For the 510 series, they went with Marvell's controller, following in the footsteps of Crucial's C300. (I've talked with somebody from Intel research about this, it's kinda amusing.)
Crucial's earlier SSDs use a variety of controllers, but starting with the C300, they've been using Marvell's controller with custom firmware. The m4 is again the same controller, different firmware.
Samsung makes their own.
Toshiba has a heavily customized JMicron. (much much better than the stuttering 601/602 controllers)
The idea of pairing macs with samsung and intel because they're big and well-known holds no water. I wouldn't be surprised if TRIM on OSX is only available to Apple certified SSDs partly because Intel released a firmware for their highly-regarded G2s where TRIM deleted the wrong block of data. You can't expect ALL owners to know how to do a firmware update written for PCs on a Mac, so those who have the bad firmware on the G2 installed in a Mac, probably still have it. So the only solution is to play it safe. Slow, but safe.
Every SSD generation, OCZ(brand)/JMicron(controller), Intel/Intel, Intel/Marvell, Crucial/Marvell, OCZ/Sandforce, OWC/Sandforce, etc, has had reports of some mysterious deaths or scary firmware bugs. Or both. Nevertheless, as long as you're making good backups and can afford the drive in the first place, the speed is totally worth it.
With that said, I'm using a C300 256GB. It's awesome.
Friend has a Kingston V100+ on a first gen MBP, he loves it too.
