Have 45m run of double staggered Leylandii .... (no I didn't plant them)

Want to remove and plant something better ... I can obvioulsy use s
chain saw and cut down to a stump, there seems to be 2 main options to
removal of the remainder.

1. Pull out stump with a trefoil such as in this video
https://www.youtube.com/watch?v=eZjqEC_FWqo ... but how well will that
work on 20 yr old Leylandii .... typical diameter between 6 and 8 " ....
assume roots will be extensive

2. Hire a stump grinder .... HSS have a 6HP model :

or do I need something beefier such as

The trees are on a raised bank about 1.5m above ground behind a 1.2m
wall.
I can put a ramp to wheel up a 'portable' grinder .... but not something
like a bobcat or similar

Try and dig the first one out by hand?

We took down a huge Leylandii when we first moved in and found it to be
very shallow rooted so getting the stump and the main roots out was
(relatively) easy. This tree was considerably more than 6-8" diameter.

That trefoil looks fun, but does rely on something pretty big as the main
post. It also looks to be pulling upwards; I would think that you could
tear out most of the stumps by leaving a taller trunk and pulling more
sideways.

Another option (depending on access and the potential for collateral
damage) would be to hire a mini digger for the day and use the small
bucket just to grub them out.
