Help choosing which sim to buy

Hello,

I'm looking in to buying one sim (I can't afford to buy two or more!)

The criteria I've got is:
*ARS enabled
*Large area (Kings Cross sized and level of complexity)
*Mix of terminus and through working
*Scope for control decisions to be made
*Ideally a mix of routes/diverging route options
*Single player with some disruption playable (Kings Cross 2015 I've had the UF/US blocked by and lost the US/DF/a line in to KGX throughout at various points - I like the service recovery decisions)
*Mix of freight and passenger working (not essential but I like the additional factors they bring)
*Mix of local and long distance express passenger services (not essential but ideal because I like the balancing of needs)

Ive been playing Kings Cross, Brighton and Peterborough recently. I've worked the Brighton main line (2013-2014) and ECML (2014-2017).

Brighton is just too small and simple and doesn't give the option to problem solve service levels to the extent I would like.

Kings Cross is a just a bit too difficult without ARS but something akin to this would be perfect. I'm running at about 87% with some critical faults on the 2015 timetable but there have been several ACOA/wrong route/needless delays owing to my inability to scan to and from fast enough.

Peterborough was a fun challenge but like Brighton is quite a simple area.

I've narrowed it down to
*LTS - the layout would take some adjusting to from the straight line of Kings Cross. I like the mix of freight and captive passenger services however I don't know the service or area and it lacks a real mix of passenger services. It does have diverging routes but is mostly 2 track - I've never played a sim as large that's mostly 2 track so I don't know what it's like! EDIT: I think the size is good

*Three Bridges - ex BML staff, I know the area and the route to Croydon very well. Less freight but large volume of passenger services make up for it. There is a sort of mix of passenger services and some diverging routes too. It doesn't have the captive service like the local GN services on Kings Cross or LTS but there are plenty of control decisions to make that I can see. EDIT: I'm not sure if it can be played single player, it looks just a bit too big!

I'm open to other suggestions - the demos have been played. I've had a look at the West Hampstead and Wembley Sims as well. I can't get on with West Hampstead and Wembley Main is not the sort of area I'd like to control.

Experiences and thoughts of those who have played both are very valued.

Lastly, apologies if this should be in a sim specific forum!

Thanks
