They are marginally harder to mount (slightly tighter fit).
If you struggle with the non-TL, you will struggle with the TL more, whether this extra struggle means you won't be able to mount it, depends on you and your rim.
If you get enough practice you will learn little tips and tricks for mounting tubless tyres.
Such as:
* Make sure it's seating in the rim well
* Coat with soapy water
* Use straps to hold seated part of tire onto the rim whilst you manoeuvre the rest
* Start at the opposite end of the valve and finish at the valve
There are many more, but we can't really comment on whether you would struggle or not as we don't know you experience on this.
