i don't know if the wanderlust comes with patches that make it work out of the box (and how good/useful they are to you), or if your expected to still mainly create your own patches.
if its the later, then id say it 'ups the ante' - you have to be sure its for you, and have the time/inclination to make the most of it.
my personal opinion (and this is no disrespect to the wanderlust as ive never seen/heard it) is if the wanderlust appeals, id be tempted to get a bare axoloti, and play with it a bit - see if Axoloti is for you.
THEN if it is buy the wanderlust , you'll see many have more than 1 axoloti, so having a spare is not a bad thing
thats a tricky one as never seen/heard one (they are very new)
I like RebelTech, Ive got a Bela Salt which they did in collaboration with Bela.io
there range is definitely a cool concept, it fits nicely somewhere between a DIY product and a 'finished' product.
my impression with OWL in the past is that its great because its easily accessible via PureData/Faust,
but its not that powerful i.e. unlike axoloti where you'll see it running a poly synth into a reverb, with a bit of chorus,
OWL , tends to have single function patches . a reverb, or a chorus , or a synth - and they tend not to be that involved.
but I dont know, if thats just the patches , or caused by hardware limitations.
so cant really say, does it hit a sweet spot of complexity/simplicity , or is it a bit limited?
there are other options you can look at too.
Organelle - Im a real fan of this, again you can program it yourself, but there are also loads of patches - its got a great community behind it too (and I contribute to it too - both on the 'firmware' size, and also I wrote Orac )
ModDevices (moddevices.com) , this is more in someways similar to rebeltech/owl, but has a few more 'commercial patches' available for it. (more expensive too )
see it this all as a continuum
DIY ---------------------------------------------------------------------------------> 'out of the box' product
raspberryPi -> axoloti -> wanderlust -> owl -> organelle / mod devices -> H9
this is not accurate, but hopefully you get the idea... you'll also see that price point, also broadly follows this.
whats also important to note, is most of this can sound as good as the others (there are some technical limitations) , its more down to time/effort of the owner, and how much they want to play with it.
so, again, it comes back to what do you want...
Eventide are well respected effects developers, they know what they are doing , so the price of the pedal is not just the hardware but your also paying for that expertise, and their time to develops these effects.
when your buying 'community developed' effects pedal, your not paying for development of the effects/algos.
your relying on what the community has developed, and their expertise, and they do what they want, so does it match what you want
thats not to say, its not as good, for sure it can be, but theres no guarantees and it can be a 'mixed bag'.
so you might find a few FX patches, that make it wow, this is fantastic, or you might just not find what you want / need.
(that the advantage of being able to patch them yourself, you can make what you want if it doesnt exist)
(note: this is no disrespect to community patches, saying they are better/worst ... as I release stuff to the community too, so my comments are fully inclusive of my efforts )
