I don't know how much crimping you do in comparison to stripping wires and using wire nuts, but if you do more wire nuts definitely get the 908s if those are your only two options. There are many times when you need to strip wires in tighter areas working on cars and when doing home wiring, and having to get the wire end all the way to the handle located wire stripper on the 959s can sometimes be a real hassle.
That being said I would not buy either of those 2 strippers for my own use. The 908s are the better plier of the two, but they have less versatile crimping dies and they add crimping dies for cable tv coax cables (rg6 or equiv.) which most people will never need or use, especially since most coax terminations are done with compression type connectors now anyways, not crimped connectors. Stride tools/Imperial make some really nice versatile good quality crimpers that are not the best at anything, but they are very good at everything. They used to be the crimpers that Channellock re-branded as their own before they changed over to their current style strippers several years ago. I used the older Channellock (Stride re-brands) commercially and personally and they are very nice for what they are. They are currently sold under the Stride name (IE-110) but are hard to find. They are re-branded, more easily found, and cheaper under the Craftsman(82563), Crescent(WS19H), Matco(MST46E), and several other brand names. They are made in the USA. I also have the newer Craftsman re-branded version and they are every bit the same as the older Channellock version in quality. I don't think Sears carries that Craftsman model anymore, but they can be found on Ebay sometimes. If price is a concern for you, keep an eye out for one of the re-brands on Ebay for a few weeks and you should find something, or look for some used wire strippers that visually look exactly the same and are made in the USA and they will most likely be the right ones. I purchased my Craftsman branded version stripper/crimpers about a year ago NEW for $8 including shipping with very little effort on Ebay.
The Stride version crimpers/strippers have better crimp dies then the modern Channellock 908 versions by a large margin in my opinion. Compare the die shapes visually (the Channellock are all the same shape and only the size of the hole in the middle changes), the strippers are located at the tips, the tips are more narrow to fit in tighter areas, and they just work well. The only caution I would give is that unlike higher end wire strippers, these strippers only list one set of gauge numbers for the corresponding wire stripping dies. The numbers given work for stranded wire, but if you are stripping solid you need to shift over one die for the same wire gauge for it to strip cleanly. Better strippers have two columns of numbers, one for stranded wire and one for solid, but all the second set of numbers really does is shift the wire over one spot for solid.
As far as I know Stride/Imperial is the company that also makes Klein strippers, because they look and perform exactly the same in every way. I have used Klein strippers and crimpers heavily and I have not noticed any difference in quality between them and any of the other pliers that Stride makes regardless of what they are re-branded as. It all just comes down to the features they each offer and how specialized of a wire stripper they are.
The ones shown in my picture below are the model version I use and think highly of. They are excellent for general use in the automotive or homeowner field, light to moderate commercial work, or to put in a car toolbox as a do everything electrical tool for general roadside repairs.
