Just got done reading this thread. This past 3 months I have made a few purchases in both brands.
civilian
delica 4
endura 4- jigged bone damascus
stretch 2 - damascus
dragonfly
a couple pm2 and a military
940
940-1 - first production run
rift
griptillian
nitrous stryker - first production run
yes, i went a little blade crazy leading up to the holidays. Still am on a buying streak at that. Here is my opinion on both brands (take with a small grain of salt). Both produce some really nice knives. For EDC, i lean more to spyderco than BM, except for the 940 model. The 940, especially the 940-1 is a beautiful edc knife and wins through this lineup for most everyday situations. The stretch, pm2, and military are my next go to knives from what i have purchased. The pm2 especially. I got burple and it is my favorite so far and receives a lot of pocket time.
For collectibility, I like the sprint runs of spyderco, but i dislike the lack of serial numbers. The benchmade runs that are serial numbered on the blade give bm the edge (something that simple won me over and I can easily justify an extra 25$ for it). The downside is, I pause and hesitate on EDCing my serial numbered knives.
Best bang for your buck, or better value as this thread brings up, has to go to spyderco. It is an easy winner imo. For which brand has the best 1 knife for me, it would be the bm 940-1. For collectibility, I go toward BM as well. What knife brand will I stick with in 2016? probably both.
I will give spyderco another nod, but this I won't use in my evaluation. I do like the fact that they try some weird off the wall designs. This is why I bought the civilian. I really do want a spyderco reverse as well. Looking through the 2016 catalog, the nirvana looks amazing and would like to compare it to my sebenzas. I do need a southard. I do think they swing and miss a lot though. I got to handle a rubicon and it just was not for me.
As far as price rising. This is a real big issue imo for both brands. They are in a good spot right now, but if BM moves up another 10%, i probably will not be buying more BMs. My reasoning is simple. I also have CRKs, Hinderers, Medfords, Striders in my collection. This is the next step up in cost imo. If BM and Spyderco jump into that lineup, it would be really hard for me to keep purchasing their brand, knowing I could get a Sebenza or a XM 18 for like 100$ or 120$ more. Spyderco and BM need to be in the 100 - 150$ (not their delica / grip) to really keep my interest. Being in the 200 range is pushing it. The 250 range starts to upset me a bit and anything past that, I would go for something else.
If anyone is interested, I could rant longer and get into more details, but I think I said too much and am sounding preachy. Both are great brands, but any knife comes down to what you want and like. I have different tastes for my needs. My needs are very light everyday tasks mostly. Would I use a 940-1 as a hard user? no way. To peel an apple? Best apple peeler I own. No lie.
