Rockshox is a division of SRAM, famous of their suspension components (forks, dampers). The major feature of the Recon Silver RL suspension fork is based on the air spring, which is a MTB standard for better sus forks. (You'll need an MTB shock pump to adjust the damper but it is not an expensive thing). Air spring is reliable, adjustable, and the fork is more lightweight than one with steel coil damper.
The major difference between the new Vado 5.0 and Tero 5.0 is the fork travel, that is 80 mm for the former and 110 mm for the latter (the bigger the better). If you seriously think of some more ambitious off-road riding, go for the non-EQ version (it gives a lot of freedom for future tyre width selection, and makes the e-bike appropriate for off-road; temporary blade fenders could be used in need).
Now, you own an older Vado 5 with Suntour sus fork. I think it is steel coil loaded. How do you assess the ride quality on your existing Suntour suspension fork?

SRAM is the American competitor of the Japanese Shimano. SRAM components enjoy great reputation, and are generally more expensive than the Shimano equivalents (because SRAM is a smaller company). I think Specialized selected SRAM because of the supply chain issues of Shimano. The only thing I wouldn't have liked about SRAM is the "single-click shifter". Equivalent Shimano shifter allows downshifting up to three gears in a single operation; SRAM allows downshifting a gear per click. (Downshifting by single clicks is believed to be easier on the drivetrain). That is a small detail though.
Bear in mind that the brakes are SRAM, too, meaning you would need to buy SRAM specific brake pads in the future (nothing wrong about that).
Do you need to sell your Vado 5? Only to recover some money for Tero purchase? I don't think you are unhappy with your Vado?
Specialized offer the EQ version for urban riders, and that is something to consider if the city riding is, say, 90% of one's activity.
