How do you know whether your parent would be best in AL or in Long Term Care?

My 93 year old mother lives in her condo with a lot of help which is draining our funds. She has frequent UTIS which are very debilitating. She can walk a little with a walker but uses a transport chair often. She can shower herself but cannot prepare a meal or completely dress herself. She is lucid about 70 % of the time but has confusion at times, especially in late afternoon and evening. We cannot figure out whether she would do best in AL or in long term care or here with us. Any input would be welcome.
