新人问有关PADI潜水店store level问题

在PADI网站找潜水店 http://www.padi.com/scuba/locate-a-padi-dive-shop/default.aspx
然后看到有不同store level:
- Career Development Dive Centers, 5 Star Instructor Development Dive Centers and Resorts
- 5 Star Dive Centers and Dive Resorts
- Dive Shops, Dive Resorts, Dive Boats and Recreational Facilities

请问不同级别之间的区别是什么呢？是不是越高level就越好？一般爱好者考OW, AOW和fun diving需要看是哪个级别的吗？如何去挑选潜水店，是看这家店的level吗，还是主要是挑口碑好的潜水教练？
还有那些没有在PADI网站列出来的潜水店呢？
