Grateful advice on picking between these two options for 3 weeks.

A — North/South combo

Luang Prabang → Nong Khiaw/Muang Ngoy → fly to Pakse → Champasak → 4000 Islands → Vientiane

OR

B — North:

Luang Prabang → Nong Khiaw/Muang Ngoy → Luang Namtha → Gibbon Experience → Vientiane 

My start point (LP) and end point (Vientane) are fixed based on my flights.

Also happy to hear other itinerary suggestions that don't involve riding a motorbike.

4000 islands (SPD) looks great but is the rest of the South worthwhile if I don't ride a motorbike (and can't do Bolaven/Thakhek loops)?

Where would you go besides the 4000 islands? Is there enough to do in Pakse/Champasak for 3-4 days?
