Laos (pronounced LAO) is not lousy...he he.
Vientiane’s city centre is laid out in a grid of one-way streets bordered by the Mekong river and Quai Fa Ngum to the south, Samsenthai Road to the north, Chou Anou Road in the west and the Presidential Palace on the eastern edge. Everything here is easy walking distance to the Mekong and night market.
Let's compare Phnom Penh to Vientiane: Phnom Penh is larger and more expensive except for the TukTuks. Vientiane has a tranquil, almost town-like vibe, fewer tourists, and a nice climate (both cooler and less humid). Phnom Penh has more nightlife options including Bassac, a walking street. Both border the Mekong River. Both have alien languages that don't really work with common translation apps. Phnom Penh has a workout culture, while Vientiane has nice, but mostly empty gyms.
