I got my Harris Tweed Mallory jacket today and it's great. Heavyweight tweed, great construction and nicely cut. I wear a size S in the Engineered Garments jackets I've owned and the size 46 is perfect. Quality is definitely a notch above EG. Will be buying more.
Navy Harris Tweed looks awesome too but I couldn't find it in my size anywhere so that made my choice much easier. I like the herringbones better than the checked patterns. The latter seem too busy with the contrasting shoulder and elbow patches.
