Which SEO tool should I invest now? Will +Rep

I'm in the same boat as the OP and after study I'm leaning toward either Magin Submitter or looking for a good month to month on Senuke. There's a price gap and NEITHER seems to offer a reasonable lifetime price, but they have the best street cred. Venomseo Pro was also on my radar, but I'm a little shy on it because from what I've heard it is VERY new and I need a proven tool. I also considered Sick Submitter, but it looks less grounded than Magic Submitter.

Use magic Submitter & Scrape box.

You should consider Scrapebox or Xrummer with Magic submitter.

With Magic Submitter V2 you can't go wrong.

Though I can't compare it to seo link robot as I have never tried it.

Anyone know how many PC's you can run Magic Submitter on with 1 license? I can't find it anywhere on the page but would like to put it on 2 of my servers.
