Syntakt, but what next?

So, I’m fairly new to the Elektron world. Got a Syntakt for Christmas and have the bug. It has been a great box to play with but I feel I require something more and was looking for some advice/suggestions.

The music I make is either 90s-esque pop-industrial metal (NIN, Filter etc I play along to patterns with my guitar) or heavily rumbled techno. The Syntakt is almost there with helping me make these from the sofa and DAWless but not quite.

The things I feel I am missing are:
Samples. I add lots of metallic clangs etc
Resampling. Being able to resample that kick rumble would be great and not use two/three tracks to get it
Per-track effects (particularly reverb). Again to cut down on track usage for the rumble

I had been looking at a Digtakt. But then realised that the Octatrack and Analog RTM Mk2 were also contenders. I’m also within my exchange period on the Syntakt, so could trade up.

Options I thought of are:
Keep Syntakt, add Digitakt. The cheapest option (if Digi is 2nd hand). Gives samples and resampling. However, more boxes which makes it less portable and more wires on the sofa.

Keep Syntakt and add Octatrack. Is the most expensive option. I get per channel effects. resampling and samples. However this loses overbridge which I quite like for when I eventually need to get the tracks into my DAW.

Trade Syntakt for Analog Rtm Mk2. Is the second most expensive at a few hundred £ more than the Syntakt/Digitakt option. Gets all options in one box and gives most things needed. However, not sure if the sampling is as good as the Digitakt or Octatrack.

Are there any options I missed. Obviously getting all would be the best, but I do not live in that timeline.

Cheers.
