Landscape contractors

Have estimates from Redefine Landscaping and Siegel landscape and drainage. Saw some positive word of mouth on Siegel here. Both are similar amounts. Have you worked with either of these contractors? The scope of the work: ripping out some areas, grinding down a high spot (likely an old tree), grading areas of my front & back yard and some piping to assist with drainage on the right side of my property.

Probably having a lot of house work done this year but feeling burned by using Amherst Roofing who taught me a lot of lessons and questions to ask.
