I have mostly focused on alt coins that seem interesting to me but when I started back in 2014 my strategy was more focused on the current most profitable coin. I think both strategies have their merits and I'm interested in projects like this one that aim to shift mining to profitable coins.
It would be good if we could see comparable metrics between this program and others for how well they perform. I know that was a big thing back in 2014 with various websites and posts on bitcointalk reporting on what was the most profitable rather that be mixed mining or targeted.
While I'm no expert and have only been mining a couple months, on both individual coins and algoswitching programs such as this...I can offer my perspective.
I have tried (for algo-profit switching):
AwesomeMiner
Hash Augur
Nemos/NPlus
and now just started trying MindMiner two days ago.
I think they are all going to be generally pretty comparable at the end of the day (from a profit perspective). While I don't have stats for you as to which one might switch more profitably (this would be super hard/time consuming to do as the only accurate way to do it is to divide your rig into pieces and then flip pools etc. etc.), I think they would all end up within a small margin of eachother. Some have pros over others, and some have larger cons than others. At the end of the day, I think it's best to try them all and settle on the ones you feel comfortable with and, most importantly, provide the following:
a) general ease of use and ability to tweak to your liking. More ability to tweak does not necessarily mean better.
b) the pool offerings you want
c) whether you also want the ability to mine individual coins and have them paid out to your wallet (Hash Augur does this, AM too I believe).
d) the fee they charge. AM is a flat rate (depending on what features you want), HA is 1.38888% (repeating, of course), MM is 1%, Nemos is 0.5%ish).
e) (this is a big one) how responsive are the devs to user concerns/errors/etc. and in conjunction, how often do they update their software for that and new miners, tweaks, etc. MM and HA are very fast/good about this.
f) whether you need a dedicated GUI. MM does not have this, whereas the others do. This does not necessarily make MM any better or worse than others, just pointing out. If you're comfortable with making tweaks (a) via the config files, then it's not really a big thing (as long as you don't change things often).
My suggestion is try them all for a couple days at a time and see how it goes. Chances are by the end you'll know which one you want to stick with. I am just beginning tests on MM (but am admittedly being limited by an issue I posted on above that MM is fixing) to see how I rank MM amongst the others, but right now it seems promising, but does lack certain capabilities that would be nice to see eventually (being able to mine individual coins on certain pools like Pickaxe etc. if mining the individual coin is more profitable than a switcheroo pool site being one, and an easier way to make tweaks in one consolidated place another).
As for pools, I personally like Blazepool. US based, never downtime, and coins are being added all the time.
