It's not going to be possible to get a definitive answer so maybe the best approach would be to buy the Signal cables if they're at a great price and try them. Then, keep your eye out for a deal on something else you think might work, buy it and compare the two.
If you're smart about buying and you stick with well-thought-of brands you can always flip them and often not be out much more than the cost of shipping. A lot of great systems here are built that way, bargain hunting to get incremental improvements, real or perceived.
