Treating them as twins is how you buy the wrong one. OptiMonk's pricing page starts paid plans at $29 a month, with a 10,000-pageview free plan. G2 scores OptiMonk 4.8 from 157 reviews.

Features
Sumo is a bundle. Opt-in forms, share buttons, analytics, A/B tests, ecommerce hooks. The popup is one app inside that bundle. If you wanted share buttons anyway, the extra tools are free weight. If you did not, they are clutter.
OptiMonk is one job done with more campaign types: popups, bars, embedded, lucky wheel, Dynamic Content, UX Protector. No share suite. No heat map.
Integrations: both do Mailchimp, Shopify, WooCommerce. OptiMonk adds Klaviyo OAuth, HubSpot, Attentive, Postscript, GA4. Sumo's older notes mention Google Analytics and friction on smaller ESPs. Archives: OptiMonk integrations, Sumo integrations.
Pricing
OptiMonk: $0 / $29 / $99 / $249 a month, pageview meter.
Sumo's older Pro at $39 a month is 2023 research, on a subscriber meter, with a free plan that allows unlimited subscribers but keeps Sumo branding. Re-check the vendor. The meters do not convert one-to-one: a 100,000-pageview site with 8,000 subscribers is cheap on Sumo and Growth-priced on OptiMonk, or the reverse.
Who should pick OptiMonk, and who should pick Sumo?
Site owners who want share buttons and a form from one install: Sumo. Stores that want on-site conversion campaigns and will send mail from Klaviyo: OptiMonk. Product pages: OptiMonk, Sumo.
Can Sumo replace OptiMonk's gamified campaigns?
Not as a first-class lucky wheel / pick-a-gift / scratchcard set. Sumo's strength is the toolkit, not the campaign types. If the wheel is the requirement, OptiMonk (or Poptin) is the category.
Which free plan is more usable?
Both are usable in different ways. OptiMonk Free is capped at 10,000 pageviews but includes A/B tests and gamification, with the logo on. Sumo's free plan is capped by branding and missing Pro features, not by a tight pageview cap in the older notes. If traffic is the constraint, Sumo Free can last longer. If campaign types are the constraint, OptiMonk Free is richer.
Does OptiMonk include social sharing?
No. It is a popup and personalisation tool. Sumo is the one in this pair that ships share buttons. Adding OptiMonk does not replace a share widget.
