I usually use Michelin Guides but couldn't find one at short noticie for Gran Canaria.
Best point was that guide was supplied with large detailed map which was good to have as we arrived & picked up our hire car.
Good on history, poor as holiday guide.
Very limited & sometimes misleading information. Twice, we set out to find archaeological sights & couldn't find them. One recommended restaurant at Jardin Canaria looked as if it had been closed for sometime. Times given on tours were misleading, seemed to be journey times without sight-seeing allowance.
I have never used Baedecker before & won't again, willingly.
