Most topical or localized estrogen creams are prescribed to be used twice a week, which is the level at which they typically provide the most benefit with the fewest unintended consequences. If the usual application isn't helping you regain comfort, a conversation with your health care provider could be in order.
Localized estrogen is most effective for vaginal atrophy; if you have other "systemic" symptoms of menopause, like hot flashes or night sweats, systemic estrogen may be worth considering. Systemic estrogen also improves vaginal health, but because it enters the system (as opposed to "localized" estrogen), there are more overall health considerations for its use.
If we had a conversation about how you measure "more effective," I might suggest other, nonhormonal options that could be helpful to you. Moisturizers can improve tissue health, lubricants increase comfort and pleasure, warming products and vibrators enhance sensation, and massage oils encourage intimacy, for example. I encourage women to experiment with all of them!
