Which telescope is a better deal or performer?

I personally would not go for a refractor you can get reflector types for much better view

Don't get sucked in by the "high Power" 350-700X for example. 150 power is the optimum----anymore power just increases the size and atmospheric FUZZ   and you see no more detail---a Bigger Mirror the better though, to catch more light and see farther away stuff.

The longer focal length gives better resolution, the aperture, the larger the diameter the fainter objects you can see.

The 60X900 would be my choice, not that much a difference in diameter.

They do make extender Barlows, 1 1/2 or 2 X would make the shorter one a better performer.

The larger the aperture, the fainter the stuff you can see. And generally, you'll see better with a low powered (i.e., 20mm) eyepiece, not a high powered eyepiece.

At the same time, The type of telescope you that you are most likely considering are quite cheap, and usually not worth the purchase price. Wobbly tripod and mount, lots little nuts and bolts that keep the thing together. And you will invariably lose those in the dark since you need to assemble and tear down in the dark.

Instead of looking at price, you want to look at value - you may spend more, but you will get a better telescope that you will use far more frequently.

Maybe something more like this as a starter scope.

You'll need to set it on a table to use it, but it'll give a better view than with the two scopes you are currently considering.

The longer the focal length the greater the magnification. So I would opt for the one with the longer focal length.
