Firstly the GM_Suzuki alliance is very different from Nissan_Renault allaince.
Nissan's CEO is the same as Renault's CEO: CARLOS GHOSN.
So both companies r run by the same man. So one can say they can have a joint production or joint sales thing at the end of the day.
Secondly Nissan cars are far better in Quality as compared to Suzuki. Suzuki can never make an infiniti or a Skyline GTR for that matter. They just can't.
Like @toyopat says that Liana's interior is far inferior to that of a Sunny. So there u go.
And I dont think Ford is gonna maitain their position for long as Ford is suffering heavy losses everywhere.
So I guess in the end I want to say and evry1 would say Nissan and Suzuki cannot be compared at all.
