Do as you know and as it is more convenient. I can't start with <servlet-class> org.quartz.ee.servlet. QuartzInitializerServlet </servlet-class> init but when has tried spring - all has worked for 5 minutes. It is very pleased. In Quartz forum answer badly, it is lazy. In spring - it is very good. Support is much better.
