Both are plug-in devices that record hours of service. The difference that matters over three years is not the hardware, it is whether you are paying every month.
The verdict up front
Garmin eLog if you are a single truck with no fleet needs; My20 if you want tracking and support. The Garmin unit is a one-off purchase with no subscription, which for an owner-operator running one truck is usually the cheaper path over any reasonable ownership period. Subscription products bundle GPS tracking, fuel tax help and support, which are worth paying for once you have drivers to keep track of. Confirm any device is on the current FMCSA registered list before you buy it.

Choose the Garmin eLog if
You run one truck and you want the cheapest compliant path. No subscription means the cost stops after the purchase, and over two or three years that difference is real money against any monthly plan. It records duty status and does that job. It does not track vehicles for a dispatcher, because it is not trying to.
Choose the My20 if
You want more than a logging device: location tracking, fleet visibility and a support line when something stops working at eleven at night. If you are adding trucks or drivers, the subscription starts to buy things you actually need, and having someone to call about a compliance device is worth something on the day an inspector is standing at the window.
Check the registration list, not the marketing
FMCSA maintains a list of self-certified registered ELDs, and devices have been removed from it, which leaves carriers using them out of compliance and required to switch within a set window. Check the current list before purchase and check it again periodically. A device advertised as compliant is not the same as a device currently on the list.
What an ELD does not do
An ELD records duty status accurately. It does not make you compliant with hours of service, it does not plan your day, and it does not stop a violation that you drive into. It also does not remove the requirement to be able to produce records when the device fails. Run your available hours through a calculator before you take the load, not after.
These comparisons are drawn from published manufacturer specifications and the general consensus of owner reports. We have not tested these products side by side, and nothing here is legal or compliance advice. Confirm current rules with FMCSA and with the states you run.
Each device gets a full review of its own: the Garmin eLog on what the no-subscription model does and does not include, and the Konexial My20 on why the cheaper hardware stops being cheaper in the second year.
